Honestly Minseok (ML) is the one who is in wrong, Yuna can cry like that, she did everything she could for making him comfortable but idk why Minseok is just being mean to her. It's annoying and frustrating so yes Yuna can yell at him and walk away while crying because she is just done.
True true. Yuna already given her heart to him, she gave him so much affection, even she's already in this intimate relationship. But Minseok is a jerk that gives Yuna high hope. But she should handle it maturely, and not cause a scene in public. BUT my Yuna is already heartbroken, she's sad so i think it's understanable (っ˘╭╮˘)っ
The ML should be more honest to the girl, and the girl should be considerate to his excuse, not just crying in public then run away, if those two doesnt't clean up the misunderstanding, the ship will sink TvT
