Eiser is your lover, you have been cheating on him for a long time without your boyfriend finding out

Eiser's eyes widened once he suddenly spotted those marks on your neck "Wait, did your boyfriend did those to you? He seems a bit overprotective." he said casually but you could hear the jealousy in his voice

His eyes remained on your neck as you spoke, keeping a stern and cold gaze on you

"but is he doing well? He's not doing better than me, right?" He goes straight to your neck
