Osomatsu-san Boyfriend Scenarios

Pranks part one

Osomatsu
He pranks you
Hot sauce prank backfires

He thought it would be a good idea to mix hot sauce into cherry punch to give to you. However the reaction was not what he expected.

I was sitting on the couch reading as Osomatsu walked over with a glass of cherry punch. "Hey I got you a drink." I hum "thanks honey." I took the glass and took a big sip. I stop myself from swallowing and turn to Osomatsu. I knew what he did. I stood up and held his face. "What are you-"
I cut him off by kissing him and forcing the tampered drink into his mouth. He gave a muffled scream and I pull away, mouth and throat burning. I held onto Osomatsu "We are going to suffer through this together"

Let's just say he learned his lesson.

Karamatsu
You prank him.
Hickey prank

I had the sudden urge to prank my boyfriend. I decided to get Osomatsu to help. So using make up I made a hickey on my neck. Osomatsu was going to be the "culprit", I was honestly nervous how he'll react. Osomatsu said that the reason he was okay helping was simply; "I've never seen get angry at us." Well I have and I hope he doesn't freak out. So we were upstairs literally just talking till I heard the door open and close along with Karamatsu saying he was back. So I push Osomatsu into the bathroom and close the door.

Karamatsu walked in and kissed me "Hey, how are you?" I ask and he sits on the bed "I am tired and hungry. You wanna go somewhere tonight?" He asks and I act nervous "well why don't you go pick something up? You can even pick what to get." He looks at me "why are you talking like that?" I mess with my hair "What's wrong? You're acting weird." He asks standing up and walking over. "What do you mean?" I ask and he held my face "you are acting stran-What is that?" He asks

Good he noticed I thought and pull from his hold on my face "it's nothing just a bruise."
"Non Non, that's a hickey. Why the hell do you have a hickey?" He asks and I glance away as he sighs "are you cheating on me?" I ask what and he repeats himself clearly agitated. I say no "then why do you have a hickey?!" He exclaims and just like planned something was knocked over in the bathroom. I saw Karamatsu narrow his eyes and go to the door. I try to hold him back in fake desperation. He pulled away and entered the bathroom looking to the side. I heard Osomatsu give a nervous hey which may have been genuine considering the glare Karamatsu had.

"What the fuck! Are you serious!" He yelled slamming the door open the rest of the way and stormed in. He shouts the same sentence over and over as he caused Osomatsu to back out of the bathroom as Karamatsu follows. "Did he do this?!" He yelled in a beyond angry tone as we try to calm him and Osomatsu said the kicker "please don't tell
o/g/n." Karamatsu glared at him "you're dead. You're dead!" He shouts before they both ran off. I followed shouting that it had been a prank and saw him gripping Osomatsu by the collar. He looked at me and huffed "you are absolutely insane." Karamatsu says releasing the grip on Osomatsu.

Luckily he forgave me but said to never do it again. Osomatsu also learned to never anger his little brother.

Choromatsu
You prank him
Can't have kids

I didn't think this prank would be to bad. We had mentioned possibly having kids but didn't really go further on the topic. So I thought this prank would be harmless. Anyway I called him down to the living room saying it was important. When he came to the living room I took his hand and sat him down. I put on a sad sullen facade and he immediately got concerned. "What's wrong?" He asks holding my cheek with his free hand.

I took a deep breath "I went to the doctor today...my obgyn..Choromatsu." I say looking at him tearing up, yeah I can make myself cry, and whimper "he told me that because of complications with my body that I would be unable to have children." I finally say and saw his face drop. "Oh. Oh y/n come here." He says softly and hugged me gently. "It's okay. I know you wanted kids. Hell so do I but we can just adopt a child." Now I really wanted to cry. This was the sweetest, calmest way he could have reacted. "Um..Choromatsu?" He hums "how mad would you be if I said I was joking?" He chuckles

"I'm not mad then. Cause if you're joking then I'm happy that we can have kids in the future." Okay my heart is done. I tackle him back with a tight hug and a laugh as I kiss him.

Lesson learned: Choromatsu is a sweet guy who really wants to see me happy and smiling.
