It’s just the 2 MLs raped the MC, after that MC finds out his guide rank will increase when he has sex with MLs. So the MC acts like he likes MLs to sleep with them and the MLs know the truth and rape MC again. That’s the main plot so far.
For subplot
- MC’s father is a soy from another country, but he is friend with MLs’ father so MLs’ family takes care of MC since he was a child.
- MLs’ father is some kind of high ranking soldier and obsessed with having S rank son. (He wants strong sons so they can protect country) but MLs are just A rank son the father wants to do experiment on the youngest son. So black hair ML takes place in the experiment instead of his younger brother. (Red-hair ML and MC don’t know but the red-hair ML notices some needle scar on black hair.)
- The guiding compatibility between MC and black-hair ML is really and surprisingly high. (MC hasn’t seriously guided the red-hair yet)

can someone summarize what has happened so far because i dont have the nerves to reread it rn
