Pink hair is like that guy who doesn't wanna marry you but cries when you decide to leave to go get married with someone else.
The thing I don't like about what Pink Hair is doing is, he's not refusing because he's scared of sex. He's scared Sunbae will stop paying attention to him if he's bad at sex. He wants them to not have sex because he want's to try and get him in a relationship with him without the trial sex, but Sunbae already set the condition for a relationship.
It's like a guy who's scared of marriage. They wanna keep you around, but is unwilling to marry you even though they know you wanna get married. He wasted Sunbae's time and effort on him because he's scared to commit. Now Sunbae is leaving, because he's right. Someone else can give him what he wants, he doesn't have to stay with a coward who isn't brave enough to try for him. Sunbae wasn't forcing him, in fact, I think Sunbae would agree to give him more time if he didn't open his stupid mouth and talk about how he doesn't want their relationship to start with sex, cause he did give him more time in the beginning. It felt like a betrayal, like bro you already knew about my condition and you're still forcing that shit on me?
Think of it like this, you tell your bf you wanna wait until marriage to have sex and then one day he suddenly tries to force sex on you. Like you already set a condition and he wants to change it even though he said he understood. This is the same situation, but instead, Sunbae wants sex first. And Pink Hair agreed to those condition and now he wants to force Sunbae to wait and get to know each other first.
