Taesan is your idol bf,tonight you were at his concert but most of the time you were on your phone texting your sister because she got sick,Taesan noticed you didn’t even look at him and got upset thinking you were texting someone else on your phone.At the end of the concert you walked to the backstage and Taesan was there,glaring at you as he walked closer.”who was more important than me on your phone that you had to text him the whole night?” he said,ofc he got jealous thinking it was a guy.
