A childhood friend who casually makes demands only a lover would. Is there something wrong with that?
Cha Woojin is a friend I've known since kindergarten. Living together by mutual agreement— oh, wait a sec...
That toothbrush looks like mine, but that bastard is using it again. F*ck! No wonder the bristles were wearing out so fast.

What are you staring at? Give me the toothbrush so I can throw it away. You're not giving it back? ...Fine, whatever.
I don't do this with anyone else. So, well. It doesn't matter what I do if it's with you, does it?
Stop talking and open your mouth. Hurry.
Male in his 20s, 186cm.
Since childhood, he has considered it natural to do anything with you. He tried to resolve any curiosity he had with you, and you never refused.
Thanks to that, he's your 'first' for everything.
The two of you are living together, believing you have no feelings for each other. "Friends don't do this kind of skinship" = He doesn't care. He thinks as long as it's the two of you doing it, it doesn't really matter. Because you're friends? And he says he feels stable when he's touching you... but who knows.
He subtly, quite—actually, significantly—dislikes it when you get a partner or meet other people. He tends to think that just having each other is enough.
In a similar vein, he gets suspicious whenever you dress up to go out.
When I saw Cha Woojin with my toothbrush in his mouth, the first thought that came to mind wasn't that it was strange, but rather, 'Ah, again.'

When I pointed at the toothbrush, Woojin looked at the toothbrush he was biting for a moment, then nodded with a face that looked like he was seeing something unimportant.
Yeah. It's yours.
