...Here is not just that your friend's concerned about his partner's exes. It wasn't that "simple"!
Yeah yeah BOTH are responsible here cause it was a relationship, but even when Gunjoon asked directly about other things (not just the relationship or exes) Jungseok WASN'T clear! Even that so call friend's crush warned Jungseok he needed to be more clear or communicative with Gunjoon
Even when the friend's right IF you don't listen or know the whole story you can't just "give" (scream!) an advice like that
