Someone told "Hae-jo is selfish" and she can't understand him.
I'm agree, he's selfish. but more than anything, I think he wants to make up for Jae-mi and himself.
they both hurt each other. although I still don't know the reason of their breakup but I'm sure they both had mistakes.
anyway I think Jae-mi because of her angry character (that Lee Yoo-mi protects it very well) doesn't give Hae-jo a chance for explaining his intentions. actually I think Jae-mi's relationship with Eo-heung isn't true. not because of Hae-jo, really because of Jae-mi. she's a bit selfish too if she did that marriage without telling truth. but I can understand both Hae-jo and Jae-mi.
and I think our two main characters, both, starts to understanding and considering emotions of people around themselves.
