I would like to thank Mentally_Anxious for the idea!! I changed it a little because I'm not good at writing poems as you can tell in my poetry book

Midoriya's P.O.V

Monday is always hard for everyone. After sleeping in for 2 days, I had to get up early at 6 A.M. I grab my uniform and change. I quickly grab breakfast and run out the door.

Once I have entered school, I open my locker to find a neatly folded note fall on the ground. I open the note and see fancy cursive

Dear Izuku,

Hello, my sweet. You must be wondering who I am. Do not worry. I will reveal myself. Later. You must go on the clues on these notes. Please do not worry, I am not stalking you. I just already know a lot about you because you talk to me. That is your first hint; you talk to me.

I love you, my sweet pea

Mysterious Lover

I fold the note and place it inside my pocket. Who could this person be? They said I talk to them, so she must be someone in class 1-A. Well, there is Ashido, Momo, Tsu, Jiro, Uraraka, and Hagakure. I'll ask some of them when I get there.

I open up the door to class 1-A, and Jiro and Momo are all over each other. Uraraka and Tsu are holding hands, Ashido is behind me in the hall, getting some people's numbers, and Hagakure is on Ojiro's lap (I so ship em) so it can't be any of the girls. I don't talk to many other girls outside of class. I then look at the boys in the class. Kaminari is with Mineta, hitting on girls. Iida is trying to boss others around to get seated. Sato is eating a slice of cake. Kacchan and Kirishima and talking, Kirishima in his lap. Shouji is talking with Tokoyami and Sero. That leaves Todoroki. He looks like he's blushing. He looks at me and blushes even more. It might be him, but it can't. I like him so much, so it can't be. It's basically the rule of high school. The person you like is not going to like you back. I'll just wait for tomorrow.

The Next Day

I open my locker and another note is in there.

Dear Midoriya,

Clue number 2. You have been to my house before. That's all I'm giving you. Sorry, it's not a lot, baby.

I love you,

Mysterious Lover

Okay. I can rule out many people in class 1A. This leaves. Todoroki, Kacchan, Iida, Uraraka, Tsu, Kaminari, and Ashido. I can rule out Kacchan, Uraraka, and Tsu because they're taken. So it has to be either Kaminari, Ashido, Iida, or Todoroki. It most likely isn't Todoroki because someone as great as himself wouldn't like me. He's too cool and emotionless. I'm going to go with Ashido. She would pull a prank like this. I might as well start talking to her if she keeps sending me letters.

The Next Day

As I suspected, there was a letter that fluttered down from my locker as I opened the metal door.

Dear Midoriya,

Why did you spend time with Ashido yesterday and kept ignoring me? You never ignore me. I felt hurt. I don't want you to think that this is all just a prank. I really love you and I hope you feel the same. Time for the third hint, and maybe the final hint if you aren't so oblivious. I will be waiting at the west wing cherry blossom on the bench. I have something I want to give you. Meet me there tomorrow. I won't be there today because my father wants me home to train more.

I hope you know who I am. I love you Midoriya

Mysterious Lover

Wait. This person has issues with their father. The only people I really ignored yesterday were Kacchan and Todoroki. It can't be Kacchan because he's taken. It has to be Todoroki. He's the only one I know that has issues with his father. But can it really be him? I actually really like him and I never knew he could like me back. I decide to walk up to him, note in my hand and a flushed face

"H-hey Todoroki," I speak, tilting my head to the ground while looking up a bit to see his face. He looks at me, a small blush on his face. "I just wanted you to know that I know who you are," I speak to Todoroki, clutching the notes he wrote to me. He just stares at me and turns around to walk around. He freezes for a second and turns his head to face me.

"Maybe, maybe not. Looks like you'll have to wait until tomorrow," Todoroki says, continuing his walk to class. I knew it was him. I start to smile ear to ear, ecstatic for tomorrow.

The Next Day

I walk into school, ready to go to the tree. I got to school early because I'm excited. I go to my locker and see a hooded figure place a note into my locker. I rush over and open it up, grabbing the note. A rose also fell. I took it and held it close to my chest I open the note and start reading.

Dear Midoriya

It seems you cracked the puzzle. But I'm still not going to write who I am. I won't be in any classes today because I will always be at the tree, making sure you don't miss me. I am at the tree this morning, so if you are here early, you can come and meet me earlier than planned.

I love you, Izuku
Xoxo, Mysterious Lover.

I don't bother to close my locker as I drop everything and run to the cherry blossom tree in the west wing. As suspected, Todoroki is there, sitting with another rose in his hand. He looks up and sees me. Todoroki stands up and I run towards him. He catches me in my arms and spins me around. Both of us are laughing as he puts me down and hugs me.

"I love you too, Shoto," I speak, kissing Todoroki. He smiles and pulls away.

"I love you too, Izuku."

Finished! Also, it's my birthday! I'm officially 16!!!
