"Yaaa...yaaa...yaa...stop fighting you two or I'll drop you here." Threat Dong Wook to the two teenagers on the back seat. They're on the way to Lee residence to introduce Dong Wook's new girlfriend. Dong Wook was driving but Seungyeon and Jonghyun kept fighting all the way. Hana laughed out loud seeing them. 

"Noona, why are you laughing?" Jonghyun pouted.
