The ad starts off with an angry guy shouting at his classmate, "Did you make my sister cry?"
"Oh...she certainly looks nothing like you," says the other, sitting at a school desk.
Not dissuaded, the first guy continues, "Remember this, you can toy with any woman but don't toy around with my sister."
The second replies, "Oh are you the kind of guy who thinks of women as a toy?"
Angrier, the first guy pulls the second up by his shirt and says, "Aren't you arrogant!" The second man says, "Even if I'm arrogant, I'm serious about everything." He now starts walking the first guy backwards. "Do you want to know what I told your sister? I told her to forget about me. That I don't think of you like that." Now, he's in so close that it looks like they might kiss. He adds, "I prefer your older brother."
The music softens, and the guy then tuts and teases the other for his chapped lips, then puts lip balm on his former adversary's lips.
Before leaving the classroom (as the other guy is shocked) the second guy says: “Don’t forget to use it regularly so you’ll know how my lips feel like.”
The camera then pans right to see a gaggle of girls swooning over the romantic moment of the two boys.
