You had a bf named diluc he didn't show any attention towards you, but you really didn't mind.

One day, you and diluc were sitting on the couch, and you were sitting on dilucs lap, but he was on his phone scrolling through it. You were getting bored, so you texted your friend and stood up, but then diluc suddenly grabbed your waist and looked down at your phone and scoffed, and he whispered in your ear in a somewhat jealous tone

Diluc: "You're not going anywhere with that friend of yours."
