Passion has 4 books. I haven't read the novel, but I read spoilers a long time ago.
1. Passion (main story, Ilay and Tay)
2. Diaphonic Symphonia (Chris and Richard, cousin brothers)
3. Passion - Suit (fluff and sex)
4. Passion - Raga (Xinlu and Yuri)
Diaphonic Symphonia is worse than Passion. Chris has a crush on Tay, and Tay has sexual thoughts about Chris.
The novel contains rape too..

this comment is so funny LOL all you need to know is that christophe is outrageously gorgeous, and while taeui is NOT romantically attracted to christophe at all, there’s these two scenes - (1) taeui and christophe go swimming in a creek and taeui admires christophe’s body + face and has to stop his thoughts from going astray lol (2) taeui’s messing around and squishing christophe’s cheeks and he has a very brief thought where he thinks sleeping with christophe would be nice (LOLL and immediately after he thinks ‘oh god if ilay could hear my thoughts rn he’d kill me’)

One thing u need to know about tay is that he is very very ‘casual’ about sex esp prior to joining unhrdo and kristoff is really GORGEOUS, he looks ethereal and everyone always compliment his face even tay. Tay’s wanting to have sex with Chris is just a fleeting thought and it vanished right away like flash of lightning haha but that scene was still hella funny. Tay is loyal to ilay. Personally, Diasim is better than passion when it comes to iltae’s relationship and tbh i love iltae + cris dynamic theyre my fave trio theyre peak comedy.
But yea if ur uncomfortable with SA it is kinda worse than passion bc of Richard, but if ur into real enemies/rivals to lovers Chris x Richard actually serve.
I was hoping for PASSION: Diaphonic Symphonia
