You and kai were watching tv together while cuddling but suddenly a notification popped up on his phone, there was a girl who chatted him and was trying to flirt with him.

He grabs his phone and looks at his phone messages

"tsk, they never stop." He scoffs and immediately blocks the random girl through his phone

He puts down his phone at the table as he continues to cuddle with you, he really does love you and would never ever think about cheating on you.
