Oh boyyy, the sequel of surfer boy x friend's little brother kun
So seme is rich and cool (like expression less cool, and typically cool rich boy) he's a kouhai of uke.
Uke is popular cuz he's charming, he knows his charms and how to use it. He's cheeky and elegant idk..
Anyway, this senpai sleeps around a lot cuz he's hurt by his unrequited crush. (Surfer boy kun)
Seme one day decides to sleep with him when uke went horny (and depressed). Then plot Twist, seme handcuffed senpai kun
Anyway, his house is big, he wasn't serious about handcuffing, he just wants to show that he wants uke so much.
And the goldfish he wanted grew so much, so he said sth cool like.. I'll take good care of what I like forever. O M GGGGGG
