Ryusei invited you to tag along with him, Baki, and Chifuyu. You didn’t really want to go but he practically begged you to go and you didn’t really want to break his heart.

When you guys arrived to some park they brought you to some tunnel. Nobody really said anything about exploring a tunnel…

You stayed close to Ryusei as you guys walked further into the dark passage. Ryusei didn’t seem to be taking anything seriously though, he was trying to scare Chifuyu. Baji finally spoke up and said “hey guys… I think we are lost…”
