Your my Weakness

"You are the sun and i am the plant. i can't survive nor grow without any love from you"

a highschool student fell inlove with a cute lovely shorty transferee student because of the dare and he forgot that he already has a girlfriend.

so. how will he handle the situation? who will he give up? Will the the shorty lovely student keep loving him after knowing that he already has someone in his heart? or will he just stop and give up his feelings after knowing the reason of his sweet gestures?
