Wait who are the people at the end

I don't know either anyone else know them?

Jaehwan’s ex crush and sex buddy.

Ohhhhhh thx

Thnx, i was wondering about the last guy too

I think he is his brother because they have the mole on same spot if we see closer

It was the guy that Jaehwan tried to sleep with in the beginning of their relationship.

Oooh
