First, Ginu is literally the worst kind of partner to be involved with. Second, why were so many panels unnecessarily posted on two consecutive pages

God, I feel the same. Ginu's a sadist who only thought about himself. He always intended to steal Yubin's "girls" cause he was jealous. Yubin didn't care because he didn't really liked them, but Ginu never considered that.
And the main trouble of the whole story gets resolved with sex. Yubin sexually "punishes" him. Pathetic.
But u can't say u didn't like this manhwa 'cause you get thumbed down... People's so unfair.

Though I wouldn't deny ripping out an earring is painful and would bleed a lot, I don't think it would be worthy of a trip to the hospital. It would definitely require cleanup, though.
Maybe it's a clip-on or something? Or just had a shitty clasp that broke instead of tearing? You're totally right that it needed follow-up.
Ah yes, substituting for your dead twin. That's not fucking weird AT ALL.
