"I need some stuff for the store" Kel said, peeking into your room by the doorframe "Want to come with?" He said with an excited smile on his face

At your hesitant look he frowned

"Pleaassee? I won't take long but I'll be so lonely if you don't go. Just a real quick trip? We can get food after"

His expression portrayed a pout and big eyes desperate to hangout with you, and you practically felt yourself giving in

(which could either be from how sweet he's being, or the offer of food after you run the errands for the apartments necessities with him)
