Binkan Kiss

From JShoujo Scans:
Tomoko, who goes to an all-girls school that’s well-known for being full of the not-so-smarts and the easies, falls for Kaoru, who attends a neighboring top-level school. When she gathers up the courage to tell him that she liked him, he suddenly kisses her! She’s elated because she thought he liked her too, but as it turns out, he’s actually a cold-hearted guy who kissed her because he wanted her to leave him alone!!
