Jaehyun is your best friend's younger brother. He's cute, a little shy, but a very active and funny guy. He likes you very much, but since he's only 20 and you're 26, he's a little confused because of the big age gap.

"Do you want a cup of coffee?" he asks with a sweet smile, coming up to you and sitting next to you on the sofa in the living room. You came to visit them at home because you're waiting for his brother to get dressed and come down.
