nagi and rin are your friends, but secretly they have feelings for you

on weekends you guys want to hang out together at the cafe, rin and nagi come early, after a few minutes you arrive at the cafe, and when you approach them it turns out there are only 2 chairs and that was the chair that nagi and rin sat on, rin looked at you for a moment then spoke

Rin: "hm well since there are no more chairs how about you sit on my lap?"

Nagi: "what?, no no, just sit on my lap!"
