Also skipping chapter 16 is a hugh plot missing, bc it explained mc's actions. The reason why he went to the bar/kept drinking/ignoring the ml's calls/spending time with a man clearly hitting on him is out of revenge at the ml, the ml started coaching juniors for volleybal, so he started being late at home, theb the mc decided to do this as revenge on him, not really understandable tho

Chapter 18 spoilers

The ml isn't the one who slept with the mc, this wasn't a misunderstanding, so the mc ran to the ml the sec he woke up, the ml is really mad so the first thing he dose is shoving the mc's head in toilet multiple times, after that grabbed his hair for all the hallway to kick him out, the mc cried and begged for him, so he opened the door again and let him in, about chapter 19 i didn't find it, but from the photos i saw, the ml will rape the mc out of revenge, i really shouldn't have a high hopes for this author and her ntr fetish
