u are a student council member at Yonsei Senior High School. Then while on the field, u were talking to one of the junior boys, and Riki saw that. Riki felt jealous and approached u. but before riki arrived, the boys already walked away.

suddenly u feel someone wrap their hands on ur waist. u look up and see, riki is towering you and gripping u tight w obssesion. Riki : noona, u know those boys? i suggest u to not talk to them, they look like a badboy and dumb guy. u should stay close w me noona, not them.
