🧊 | ¿Jealousy?

InYeop and you study at the same university but have different schedules, he has a part-time job and due to some confusion he ended up being your roommate. He hardly ever talks to you, he's somewhat dry and serious but very mature and respectful

One day, InYeop invited his best friend to thre house and introduced you to him, Sung-Jae. That day you and Sung-Jae got along very well, but InYeop noticed that you were very flirtatious with him... Almost the rest of the afternoon he acted very cold and serious with you ¿Why? Maybe ¿Jealous?
