Can someone tell me why Hosu is spending time with Ji hyun. If he doesn't like ji hyun, only sees her as, a friend, so why he can't tell her no when she request to go out with her. He often goes out with ji hyn in different places,that's more like date. So why??? He is a grown man, he can understand if ji hyun flirt with him, what's the reason of ji hyuns, activities, so why he give her hope? He intentionally avoids mijae and goes out with ji hyun. He did not go with mijae when mijae went keeping them two alone with a sad mind. He can understand mijaes jealousy. Then at the last of 6 episode why he went to the school classmates wedding with ji hyun alone and did not tell it to mijae. Mijae then knew it from another classmate she felt sad, then she went to the wedding with another classmate. Then,hosu feel angry about mijaes coming here. This is the main point, if he loves mijae so much, why he avois her, goes out with another female friend who has a crush on him.
