Well, we start with Izuku and Kyouka heading to his house, but that wasn't the only problem, as luck would have it, it started raining, and they were forced to stop at a store for Izuku to buy an umbrella. Despite all these things happening, Izuku and Kyouka were having fun with each other, even though they were wet and cold. However, not everything is fun because now it's getting to a serious topic.

Kyouka: G-guy, what am I going to do with my clothes? I-I don't have anything to wear when we get there. I think I'll have to use Inko-san's clothes.
-She said, shivering a bit-

Izuku, a bit embarrassed: I'm not going to give you my mom's clothes, so I'll lend you some of m-my clothes.
-Suddenly, Kyouka starts giggling, imagining yourself wearing the ''shirts'' shirts
-What a-what are you laughing at?
 -He asked, blushing-

Kyouka: Nothing, just imagining you giving me one of those 'shirts' of yours.
-After that, she had a question she always wanted to ask-
By the way, where do you get those shirts?
-He just shrugged, which made her a little annoyed and made her take revenge by poking his side, making him jump in surprise.-

Izuku: Darn!
-He cursed himself while turning pale for this slip-up he made-

Kyouka: You... do you have ticklish ?
-She asked, with a sadistic smile, because in all these years, Izuku has never shown to be ticklish! This was great news for her!-

Izuku: B-be-LOOK! WE'RE HERE!
-As soon as Izuku grabbed the key and opened the door, a woman very much like him appeared.-

Inko: Izuku!
-She grabbed him and took him in a bone-crushing hug.-

Izuku: M-mom! I can't breathe! -
He said quickly, starting to turn blue.-
After he spoke, she let him go so he could get the air he needed and turned towards the door to welcome a very pleasant visitor.

Inko: Kyouka-chan! Welcome!
-She said with a smile.- 

Kyouka: T-thank you, Inko-san.
-She returned the smile.-

Izuku quickly recovered and faced his mother.

Izuku: M-mom, can I ask a question? It's about something important.

 Inko: Eh? Of course, but about what? And how did you two get here all wet? I gave you an umbrella, so why didn't you use it?
-She asked with her head slightly tilted.- 

Izuku: Her parents went on a trip to a rock concert without telling her, and she had nowhere to stay these days. Can she stay with us? And about the umbrella... I didn't consider that it would actually start raining.
-Izuku scratched his neck.-
 And about Kyouka, could she sleep here? 

Kyouka nodded and bowed to Inko.

Kyouka: "I would be very grateful if you could help me."

Inko: O-of course you can stay! And please, if you need any assistance, I have no problem helping you.
-She spoke with a smile on her face.-
You'll be in Izuku's room, no problem, right? And next time, take the umbrella, Izuku!

Izuku: Okay! Thanks, Mom!
-Izuku said with a smile and hugged his mother, which she returned with a huge smile on her face.

Kyouka, despite being happy with the scene in front of her and the fact that she could sleep there, a part of her didn't like the fact that Izuku had to give up his bed for her, but for now, she wasn't going to say anything. 

After that, with everything sorted out, Inko began to prepare dinner, and Kyouka had to wait for Izuku to come down with the towel and clothes, which didn't take long for him to do.

Izuku: Here, Kyouka.
-He said with a smile- 

Kyouka: Thanks, Izuku. Are you sure you don't want to go first?
-She asked, concerned- 

Izuku: Nah, you can go first. Unfortunately, that rain mostly got you, and there's the fact that I didn't bring the umbrella. The least I can do is let you go first so there's no risk of you catching a cold.

Kyouka: But you can catch a cold too, right? And it's not your fault for not bringing it; none of us considered it would rain, except maybe Inko-san.

Izuku: I know. I think she can predict the future, but now it's your turn to shower.

So, albeit reluctantly, Kyouka passed by him and entered the bathroom. Once she was inside, Izuku approached and placed a laundry basket by the door. He knocked on the door to get her attention.

Izuku: Kyouka? There's a basket outside where you can put your clothes.

Kyouka: ...Thank you, Izuku.

After that, Izuku went to the kitchen to make hot tea for both of them.

 He didn't have to wait long when he heard the water turn off and the bathroom door open. Kyouka entered the room, wearing the clothes Izuku gave her. Once done, she looked to find him sitting in the kitchen chair.

She observed the boy, pondering on how he seemed lost in his thoughts. This had been happening more often than usual, raising a concern in her head.

Kyouka: Are you okay? You seem lost.
-She said, snapping him out of his thoughts while gently poking his side. He turned slowly toward her, noticing her in his 'shirt' shirt...She looked super cute. Feeling a bit embarrassed by him looking at her that way, Kyouka turned her head slightly to the side so he wouldn't notice that she was starting to blush. Fortunately for her, Izuku didn't seem to notice.

Izuku: S-sorry, I... was thinking about what movie we can watch. 'I'm sorry, Kyouka.' I'll take a shower, wait a bit, okay?

Kyouka: Alright... 'His heartbeat... Why is he lying? He says he was just thinking about a movie, but it doesn't make sense for him to lie just about a movie.'

After this dialogue, Izuku went to take a shower, and Inko invited Kyouka to eat, which she accepted immediately.

Timeskip of a few hours

After showering, Izuku was called by his mother for dinner, and after they finished eating, Inko mentioned she was going to sleep. She went to her room, leaving Izuku and Kyouka alone to watch any movie they wanted. After a few minutes, Kyouka ended up falling asleep, clinging to Izuku, while he watched the rest of the movie completely focused. When it ended, Izuku checked on her and noticed the peaceful way she slept. Determined not to wake her, he picked her up, as gently as he could, in a bridal carry, and took her to her room. He laid her on her bed, ensuring she was comfortable. He was about to leave the room, intending to sleep on the couch so as not to make her uncomfortable, but that wasn't his fate.

Kyouka: I-Izuku?
-A whisper that made him turn and face her.-
Thank you.

Izuku: O-oh? Did I wake you up? I'm sorry... but why are you thanking me?

Kyouka: No, it's okay, just... Thank you for today. For helping me. I feel bad that you're giving up your bed for me.

Izuku: No need to thank me, Kyouka. I'm happy to be able to help you. You're one of the most important people to me.

This declaration made both of them blush.

Kyouka: Y-you're also one of the most important people to me.
-After that, she thought about what he said and decided to ask.-
Am I more important than your mom?
 -She asked, teasingly. He just laughed and shook his head.-
I can still try.

Izuku: Yes, you can't beat her.
-He said, laughing lightly. He prepared to leave; it was getting very late.-
Good night, Kyouka.

About to leave, Kyouka thought about it. He didn't need to sleep on the couch; his bed was big enough for two people. Would it be cramped? Yes, but she didn't mind.

Kyouka, blushing: You don't need to sleep on the couch.
-He stopped leaving the room the moment she started saying those words. Obviously, he was confused; where else would he sleep if not on the couch? Kyouka realized this and began to explain where he would sleep.-
V-you can stay here with me. I know it would be weird, but it's your room, dude. Just don't try anything, okay?

Izuku was obviously surprised; he didn't expect this. He didn't expect her to be so comfortable with him to the point of letting him sleep in the same bed as her. This made both of them blush.

Izuku: A-are you sure? I don't mind sleeping on the couch...

Annoyed by his persistent refusal, Kyouka got up, pulled him onto the bed.

Kyouka: J-just be quiet and go to sleep!
-Kyouka whispered to him, getting closer to snuggle. Obviously, this made both of them blush, but it gradually faded.-
And Izuku? T-thank you.

Izuku: You don't need to thank me again for wanting to help you, Kyouka.

Kyouka: 'I'm not just thanking him for letting me stay here; this thank you is also for what he did earlier for me.'
-That's what she thought.-
 I know...

After that, she rested her head on Izuku's chest and fell asleep. Unconsciously, Izuku protectively held her in his arms and also drifted into sleep.
