-

You had never questioned your relationship with Gakushuu. Ever since you found out that the two of you were soulmates, you figured that it was what it was. Fate. You were sure the red string attached to both your pinkies had signified that.

It was only after a conversation with a friend, had you began doubting yourself.

"What? You broke up with him?"

"Yeah. I found my soulmate, remember?" Your friend, Ami stated as she took a sip out of the coffee you had just prepared for her.

"But the two of you have been a thing for years! Weren't you talking about marriage at one point?" You had your mouth agape, shocked by her nonchalant response.

"Well, yes, but you can't expect me to continue loving him when i've already found the one I'm supposed to be with. Besides, we knew we weren't going to spend the rest of our lives together anyways."

You blinked at the girl as a wave of different thoughts rushed through your mind.

"Ami, you barely know the guy! How do you know he's gonna make you as happy as you were when you were with Karma?" You blurted out, feeling slightly frustrated at her prompt decision. "You're throwing six whole years down the drain!"

Ami only stared at you, unfazed by your sudden outburst. Letting out a sigh, she gently held your hand and gave you a small smile. "(Y/N), you need to know that it can't be helped. After 25 years, I finally know who I'm soul bound to– and I'm not letting him go just because I met him later than I should have."

"Karma played a huge role in my life and I cannot emphasise how grateful I am for his company and affection. I'll still continue to love him, but I will love my soulmate even more, whether I like it or not. You're lucky you and Asano found each other in junior high, y'know? You guys could love each other since the start, and you'll have no qualms about it. You don't have to go through the pain of thinking of another, fearing when your current relationship would end."

The room fell dead silent. Before you could even speak up about your thoughts, Ami had already changed the subject.

You now sat on the couch with your loving husband, feeling rather cozy as you rested in his embrace. Gakushuu had his right arm wrapped around your shoulder while the other was occupied with a novel. The television was on for your own entertainment, yet your mind could barely concentrate on the local news which was being reported.

Every now and then, Gakushuu would turn away from his book to check up on you, or even to just show some love and affection. Usually, it would be in the form of small kisses on the lip or forehead. Though this time, he had noticed that your behaviour was off. You were the staring at the same vase on the coffee table for the past 5 minutes, and nor did he feel you snuggle close to him for the past 10.

With the bookmark you had got for him a few years back, he slot it in between the pages he was reading and set the novel on the table. You still hadn't budged.

He then took the remote control and pressed the red power switch at the top right hand corner. Upon the sudden silence, you looked up from the vase and turned your attention the the strawberry blonde.

"Hey, I was watching that!"

Gakushuu raised an eyebrow. "Were you?"

Slowly leaning your body back to the couch's backrest, you responded. "Yeah..."

Clearly, he wasn't convinced. With a soft look, he tapped his thigh, inviting you to sit on his lap. But to his surprise, you shook your head and rejected his offer.

Gakushuu frowned, realising that this was much serious than what he had originally thought. Through analysing your behaviour, he concluded that you weren't mad. At least, not with him.

"Is something on your mind, dear?" He spoke.

You kept quiet when he asked. Your eyes were not on him, but were fixated on your pinky. He saw you rubbing the area where the string was wrapped around your finger, watching as you dazed off in front of him.

"At least tell me if it's anything I need to be concerned about. I can give you space to collect your thoughts if you wish."

Taking a deep breath, you moved closer to your husband, resting your head on his shoulder while he brushed the few strands of hair which fell on your face. "I've just been thinking..." Your eyes were still on your pinky, still feeling uneasy. Gakushuu noticed, and started to give you light pecks on the side of your head.

"Mmm, go on." He said between kisses.

"Would we still be in love, even if we weren't soulmates?"

Gakushuu ceased what he was doing and proceeded to look at you in the eye. You stared at him, mildly afraid of his response.

"Why ask such a question?"

"I saw Ami the other day."

"Akabane's girlfriend?"

"Ex girlfriend."

His lips slightly parted, surprised by the new title.

"She found her soulmate a few days back." Gakushuu listened to your story. "And immediately broke up with Karma so that she can be with the guy."

You sighed, wondering how you would take the news if you were in the red head's position. "I dunno... It just got me thinking."

"If we weren't connected by this stupid string, would we even be where we are right now? It sounds stupid to say, but are we just in love because we're supposed to? Are we just forced to be attracted to each other because of our connection?"

Gakushuu readjusted himself to face your direction, eyes looking more serious than usual. "Do you feel that way?"

Confused, you turned to look at him. "Do you feel forced to be in love with me?"

With no hesitation, you immediately shot up, placing a hand on his thigh in the process. "No! Definitely not! I love you unconditionally, with all my heart!"

"So why is there a need to ponder over the possibility of our relationship lasting due to being soul bound, when ironically, there are no strings attached?" After hearing Gakushuu's words, you relaxed your once tense shoulders. A moment of silence passed as you did.

Taking your hand which was originally on his thigh, he began to rub small and slow circles on the back of it, as well as giving it a gentle peck before continuing. "I love you so much and no 'red string of fate' is going to determine that. Everyone is different. Some may be easily swayed by this concept and mentality of being soul bound, but we are not like that. Believe me when I say that we will stick together even if this string unexpectedly fades one day."

You smiled, while finally accepting a long overdue offer. Getting up from the couch, you placed a knee on the space in between his thighs. Gakushuu definitely gets the memo as he welcomes you to his lap with open arms. You grinned. Your arms were now wrapped around his neck, straddling him as his own arms snaked around your waist.

"Yeah, you're not gonna get rid of me that easily." You joked, earning an amused laugh from your husband.

"I never planned to in the first place."

Gakushuu says before pulling you into a deep kiss. Your passionate kiss soon turned into a full on make out session which inevitably, ends up in the bedroom with the two of you gasping for breath.

"God, I love you so much Shuu." You say as the male leaves a trail of love bites down your collarbone, a wave of pleasure coursing through your body upon each contact the strawberry blonde makes with your skin.

"I love you so much too, darling."
