it was a oneshot although im not sure if it's included in another work or its own thing on here

uke and his sister are identical twins (either that or they are easily mistaken for each other) and his sister is eloping to marry her fiancée, but the fiancée's brother (seme) is seemingly against their marriage

so when the seme approached the uke with intentions of confining him so that he "couldn't marry his brother", he pretended to be his sister so that she wouldn't actually have to be the one to be held captive by the seme

yada yada yada the sister and her partner came back for the uke and as they were about to all run away together, the seme desperately tells them to not take him away (i think he pulled the uke back when he was about to go on the elevator with his sis and her partner) and they all realised that he was in love with the uke and the uke tells them that he'll be alright and then they go back to fuck

confinement aside, the seme wasn't actually all that dangerous - like the confinement was that the uke couldn't leave through the apartment and have contact outside but otherwise he could've done whatever in the apartment

it is a yaoi/bl set in highschool, i remember a scene going like this

one of the characters is trying hard to be cool but whenever he does, the guy he's trying to pursue ignores him but when he lets himself get messed around with and turned cute by the girl classmates, the guy looks his way

this sequence happens a couple of times and he figures out that the guy likes cute things

besides from that i dont remember much,,
