This one actually a decent story since the personality traits of the characters was built quite firmly. It’s better than most of no-brain-plot Korean BLs. An explaining for anyone who’s still confused:
Seme and uke are in love, but seme is hesitant to take their relationship further as long as coming out to his sister, who means everything to him as the only family he has left. Uke though hurt tries to be understanding and patient.
After a heated argument, uke goes to the bar where seme works to wait for him. Instead of seme, his sister shows up. She’s instantly drawn to uke and even suggests they should date. Uke being honest tells her that he loves the seme, but they aren’t official yet because seme is afraid to initiate it. Hearing this, seme’s sister sees an opportunity and decides to go after uke, thinking she can win him over since them two hasn’t made it official and considering it’s just a joke. She even goes as far as proposing marriage.
Uke quickly realizes her true nature - selfish and shameless, willing to steal her own brother’s love and happiness for herself. He feels for seme, who idolizes his sister while she clearly doesn’t have the same regard for him. So uke hatches a plan: he agrees to marry her, but on the condition that they won’t be intimate and that seme must live with them. Seme’s sister confident she can eventually win uke over and also to spite on both seme and uke that the man is now her official husband and that little brother is a good boy listens to her.
However, living together doesn’t go the way she planned. Uke takes every chance to show affection to seme right in front of her, making it clear where his heart truly lies. The constant displays of affection - kissing, touching, and even more intimate moments (the bj that was so HOT) are constant reminders and threatens to her that she’ll never be able to stand a chance. Eventually the woman can’t take it anymore and demands a divorce, the two broke up and now the sister hating on seme and wanting to breach her family tie with seme.
Uke’s marriage to seme’s sister served 3 purposes: to punish her, to expose her true nature to seme, and most importantly, to make seme realize that uke is his only true dependence. Uke’s affection for seme is deep and fierce; when he saw seme’s sister’s shameless behavior, he turned the tables, removing her influence and securing his place by seme’s side once and for all.
The uke was amazing :) going all for his baby. The only bitch here is the sister, she deserved that. Don’t talk to me oh she’s a woman she was lied no she knew it from the beginning and still went for hurting everyone. And I came for men, idgaf on women :)
