So i guess there are 4 series of this drama. It starts out kinda slow but don't give up. The moment the sister goes to the bar the story gets better. The big bro is just something else. Hes a flirt at work but his girlfriend is from hell. Shes got princess syndrome and he doesnt seem to be bothered. She gets so annoying you wanna slap both of them The sister is a tomboy and does jiujitsu so shes though as nails but shes still a girl inside. Her mouth expression is funny Baby brother is just pain weird. Hes a nerd and he follows aliens Hao yang ( the boyfriend) is eye candy esp with his eyeliner and he does great with his hopeless romantic side. Hes a total playercand heart breaker. The parents are a mess esp the dad but everything works out for all of them in the end
