kdrama lover

I actually loved this k drama alot ! but after some time I suddenly started feeling bad because basically there are two characters that is Han seo-jun and Lee su ho they both fell for the same girl which is the main lead named Lim ju kyung but Lee su ho will end up with her but about seo jun I really feel bad for him I did not like how seo jun was treated he deserved way better but it is just a K-drama I guess but I did not like the way he was treated at all he deserved batter way better
