I read the raws up to chapter 45+ Eugene/mido eventually will admit that he's in love with ji chan and that he lost against ji chan but things only went downhill from that moment for ji chan (he even lost the spark in his eyes later which is no surprised)

Ml confessed thats he's mido but ji chan couldn't accept it, so he (ml) went crazy he became anxious and possesive, R4ped mc, locked him, and even break his ankle... I don't think he regret what he did to ji chan yet he think thats the only right thing he could do since ji chan hates him
Close enough, welcome back gojo
