    You and Su-hyeok, your boyfriend, are making your way to your classroom when suddenly On-jo went infront of Su-hyeok and greeted him while you ignored her and walked past them, she was about to say something else to Su-hyeok when he walked passed her to follow you which upsets On-jo a bit. You and Su-hyeok were walking up the stairs when On-jo interrupted you guys again and went to stand infront of you.

    "Meet me at the rooftop." She told Su-hyeok.

    "But I don't fight anymore." Su-hyeok replied.

    "I just need to talk to you." She replied.

    As she was about to walk up the stairs she suddenly tripped making you chuckle quietly as Su-hyeok nudges you a bit, On-jo stood up annoyed and ran away.

    "What's wrong with her? LOL" You said.

    "I don't know." Su-hyeok replied.

    You both ignored it and went to class which is also the same as On-jo's class.
