You boarded the bus during a school trip, and found that there were no seats at all. You went to the end and looked, but you didn't notice anything. Your cold but serious classmate noticed you even though he was holding his phone and listening to music.

He got up from his seat and stood next to you so you could sit down. You sat down, and he just stood there. at one point, a guy with a friend came up to you and said. “hey you, stand up.”

to which Riki replied. “…This is her place”
