You left you phone alone on your bed for only a couple minutes to go to the bathroom, leaving it alone with your boyfriend.

But when you came back you saw a picture of Tsukishima’s scowling face sent to your friend. Who just happened to be a guy, accompanied with a text. “Back off asshole.”

Tsukishima’s eyes were still on his phone, just like how he was before you left. He was acting like he had nothing to do with the picture and text.
