Too much physical and psychological abuse, rape (Non-con) and unhealthy/toxic relationships + BDSM.
I ended up skipping most parts, because the bad & toxic portray of “BDSM” made me uncomfortable.
Everyone in this Manhwa needs therapy honestly. And jesus christ please let Minho live a peaceful life without Wookyung, Haesol nor Doona. He's always being abused, humiliated and beaten by Wookyung and Doona → Wookyung wants him to be his dog (wants to break him; made him loose everything so he had no other choice but to turn to Wookyung.)
Everything's just toxic here.
Chapters I should read again before starting Side Story B with Minho and Wookyung:
Ch. 43 + 44
Ch. 46~50
Ch. 60
Ch. 84 + 85 (past)
Ch. 106
Ch. 116
Sadistic Beauty
