he didn’t lie he told her why lol
but he didnt correct her when she asked why he was nice to her despite not being her manitto. he knew he was her manitto and that was the real reason he was nice to her at first and he didnt tell her that. so he did lie to her.
so he was her mannito?
yes, he was her manitto. everyone supposed to get only one person as their manitto but there was a mistake and jiyoon ended up with two manittos, joonyoung and the other dude with glasses. the glasses guy was later revealed to be her manitto hence why jiyoon thought joonyoung is not hers and joonyoung never revealed he was her manitto too.
her not liking people who lies and him not truthfully admit he was actually her manitto is probably gonna bit him in the ass. hope not too much trouble gonna come upon them.
