wtf, I'm so confused rn. Who's the real lover of the gray hair dude?! bcs he said he doesn't like cheating but he kissed the military guy while he's in a relationship with the blue guy ?!!! and he used to bring girls in their house

author didn't really specify if it, but i do lowkey think it might lean towards Kihun (blue-haired guy) since they did like each other but broke up because of a misunderstanding and Kihun still clearly loves him. they broke up bc silver guy thought he was cheated on by him with his sister (misunderstanding) so he kissed the military and had sex with other people after that (early chapters where Haekyong ran into them).

My theory is the fl got reincarnated (bcs of her memories) and this life she want to save the duke bcs how tf she didn't die when she drink the poison ?! some reincarnation stories is like that, they didn't die bcs they're already immune or already died in their past life so drinking poison doesn't affect her anymore (just my theory) and the black haired dude ? she doesn't remember him ?!

kinda agree with you that she might be reincarnated, coz they showed a scene where the duke kinda has a messy appearance(?)
but I'm thinking that she was raised as an assassin or something together with the black haired dude. But just forget about it, like maybe she had an accident during a mission and had ammesia??
ngl I got scared when it's his time to speak bro I thought he's gonna confess his love
