Never I've been rooting a red flag seme but the uke is the reddest flag in the whole story. The chap 1 foreshadowing uke received karma for all his and his family shits they did to Heeseo family. He should have leave Heeseo alone and let him live peacefully without those toxic foster parents using him as cash cow to exploit. Bro is hypocrite, he didn't even put his mother in prison for the crime she'd done.
EDIT: I know grape is bad, but Taekyung's indecisiveness ruined his and Heeseo life. His mother should be imprisoned for murdering Heeseo's mother. If he was smarter like any decent ukes of manhwa, he would dumped Heeseo to therapy, left him alone to live in peace and send the murderer to jail without caring that is his parent, crime is crime. That's how he should show remorse not paying and giving child support, stalking and asking about Heeseo situation like some creepy old man just because he feel guilty not sending his criminal parent to jail. He deserves all the hate like any toxic red flag seme and uke. Heeseo is by no innocent and actions are not excusable but he is a victim of sh*tty people, Taekyung, the foster parents, and Taekyung's mother. Let them hurt each other, each have consequences of their own actions.
According to some commenters, toxic x toxic, too much drama, too much SA, too much idiocy, and the plot is not very good or maybe the translations need to be proofread because it's bad.
I read, skimmed, and it is what the commenters said.
