Lmao wtf, Hiroki got pissed when he found out Rui with Ayumi, but didn't he do worse than that? Like had affair with a married man. Disgusting.
I know it's a fiction, but unfortunately there many cases like this in rl. I mean idc how much you're in love with someone, but if they're married or taken, its time to back off. You'll ruin someone's else mentally and physically, and that's not okay at all. Control your ego.
Anyway, their character development sucks as well.
Agree with your but sis, both of them are at fault tbh. Lol. The mc need to value himself more. He can actually stop before it gets worse, but he fell into the temptation, got carried away after knowing that man is married.
At least he needs to have some self restrains. After he found out that man is cheating scum, he really needs to run away. But loook at him, continued the toxic relationship and got hurt. :| Like no matter how lonely you are, dont let yourself stood so low.
My theory is, that Tae Seongjae' is not the real one. I guess the Sunbae got transmigrated as tsj, that's why his behavior is different from the novel. I hope it's true. I feel so bad for the mc. It's pitiful when he said he had nothing. ╥﹏╥
