Am I crazy?

no cause why is that so accurate

Isn't that his childhood friedn that he hooked up with, and their parents walked in on them, way before he met Garam?

Chapter 9 for reference. I think that's her, but I can't tell, cause I can't see her mole near her mouth to be sure that's his friend he hooked up with once

OMG I THINK IT IS

She’s his friend, idk about them hooking up before tbh. But he ran to her after realising his feelings and got advice from her

Check chapter 9. I think it's the same girl/female friend that he hooked up with

But yeah it says "the time he had sex with his childhood friend and he got caught by their parents" I'm pretty sure it's the same girl, as he's only comfortable with her given their circumstances and if he says her name in the next chap, it's definitely that female friend

I took a look at the raws, and with my Korean skills, I was right on who the girl is.

Okay but I don’t really get why that matters tho? They didn’t hook up since meeting garam and they are obviously not into each other ^_^

I didn't say it did? I'm just saying who she was before Jaehyuk/Garam were a thing, and that the girl who the person above asked who she was, and I was just saying that its the female friend from the beginning of the story.

And I said that cause you said you didn't remember them "hooking up before". I didn't say she will come between the main characters, or that it mattered just to clarify.

Jaehuyk only has one girlfriend and it's this girl. We've only seen him with her. She's his childhood friend. They hooked up one time and got caught by their parents which resulted in Jaehuyk being financially deprived by his parents ever since lol That's why he ended up at the dorm with Garam. He always goes to her for advice and he already told her about Garam except he never mentioned it's a guy xD Also she has a boyfriend now and they're madly in love

Yup! Everything you said!
