Hyunjin is your desk neighbor, he was very kind and sweet. he always helped you if you didn’t understand something. and you considered him the most friendly and cold-blooded guy in the class.

and then one day, walking along the school corridor, you notice Hyunjin with some girl who was putting his hair in a ponytail with a smile, and Hyunjin was smiling and talking to her. you started to get a little jealous of Hyunjin, so you decided to talk to him, only later.
