Nagi was your boyfriend, he always lazy around but you always okay with that because he still gave you enough attention you deserve.
One day, you mad towards him because he ate another girl lunch when you already brought him lunch, you clearly heartbroken because you feel he doesn't value your food.
So Infront of him, you gave your cooking to Sae, even you feed Sae Infront of Nagi itself, it's made Nagi jealous beyond limit.
In the end of the school, he pulled you into empty classroom, and he immediately pinned you on the wall, you though he would be angry, but no.. he cried Infront of you while his head hanging low.
"B-babe.. I'm sorry...I thought you didn't cooked me lunch... if I knew you made me lunch.. I would throw that disgusting food away.."
He spoke while sobbing so much.
