What is the name of this song from Sekaiichi Hatsukoi? I recently was looking at the Sekaiichi Hatsukoi OST and I came across this one I really liked. Video is here from YouTube.

Just for reference it plays during Season 1, Episode 12 of Sekaiichi Hatsukoi and I was able to find the scene here.

Does anyone know the name of the song playing?
You're most likely looking for 恋は切なく (Koi Wa Setsunaku, Love is Painful), track 15 of OST 1:
