Can someone plz explain what happened in chapter 61

Shiwoo is just in bed all the time and yujin asks if he is bored and wants to have sex
Shiwoo saids if yujin want to they can do it so yujin puts his fingers in..
Yujin says things like 'do you like it here?' 'If you want to stop or if it hurts say it right away'
Obviously yujin mean it in a caring way and shiwoo likes being touched by yujin but since shiwoo is mentally unstable he is really worried that if he react a lot yujin will think he is a slut or get mad or sth and starts crying
Yujin asks why are you crying and this disturbs shiwoo even more because his ex used to ask that before abusing shiwoo(yujin asked because he was worried tho)
Yujin says its okay and to forget about everything and focus on feeling good
People who dont speak korean well but read the raws are misinterpreting the story a lot..lol
The last chapters are far from rape and i know cause korean is my first language

Thank u XD
Thought Yujin raped him or something
+ Sometimes I want to learn Korean just to understand manhwas lol
