What makes it worse is that she kept lying to Maya about it even after they worked out their problems and still never even told her until the MC did. I do really like Josy but it was a really shitty thing to do and I don't think she should have been forgiven so quickly for it. I probably wouldn't like her anymore if she did it to any other character but I really couldn't care less about what happens to Maya so I'm not too bothered by it. If she did that to the MC though she would be right up the top of my most hated character list with Maya.
As I understand it, Josy and Maya had not met for a long time and were about to leave. But this had to be done when meeting, when Josy gets to college and meets in person. Josy was already driving to MC to stay with him! (Before arriving, Josy called and talked to MC. She said she was coming. Notice, Josy called exactly and only to MC! Because Josy came to be with MC!)
She did not know that she was going into the room to Maya (she was sent there). And then this unexpected meeting. She did not know what to do (what to do in this situation).
Therefore, in the bath she asks MC for advice. She says what will we do? Notice, she said “we”, because for her “we” is Josy + MC! Instead of deciding what to do together, MC just ran out.
And only after that, Josy and Maya talked all night and decided to settle relations between themselves.
MC with Josy, after that they chatted (chat). Josy explained to him that this (the restoration of Josy’s relationship with Maya) happened after the MC ran out (after they talked all night.)
Josy also said in the chat that MC was more than a friend to her!
Thus, if MC didn’t run out but figure it out, then there wouldn’t be a Josy talk with Maya all night and as a result of this there wouldn’t be a restoration of Josy’s relationship with Maya. - And at the beginning of Ep.4, Josy and MC would be together!
Josy was hoping a happy meeting with MC would happen. They will discuss everything. That he will support her and help. And it turns out: instead of one problem, as explained with Maya, she adds more, how to reconcile with MC +. He left her in a situation where she needed help and support. In addition, she sees that he is dating other girls. Imagine her condition, she is obviously offended, painful and hard. I felt her shock state.
