You and chishiya kept your relationship discreet. Sure, you had subtle touches in public like hand holding or his hand on your waist, but neither of you denied it or admitted to it when someone asked about it

It was a hot summer day at the beach when you held chishiya's cold hands to help cool yourself down a bit

"You might as well go to the artic if it's so hot." Chishiya remarked sarcastically

Suddenly, arisu saw both of you holding hands and asked about it. Like they said, curiosity killed the cat.

"Are you guys dating?" Arisu asked

You panicked. What were you gonna say??

"Nope, just friends." You pulled your hand away from Chishiya

You could see the flash of irritation and shock on chishiya's face.

"Just friends when your neck says otherwise." Chishiya said under his breath, clearly annoyed and frustrated about it.

He then agreed with you for arisu

"Mhm. Just friends." But the way his hand twitched to grab your hand? We'll, that was no one's business.

Later, you saw chishiya with a girl on the rooftop. They were flirting.

After, you confronted chishiya about it

"I thought we were "just friends"?" Chishiya commented, still not over the incident awhile ago with arisu

Obviously, he was just flirting with the girl to rile you up.
