I like Jadoo / Hello Jadoo

Seonghun is a new transfer student who can’t run during gym class because he’s in poor health.
Since he can’t even participate in the soccer game, Jadoo feels sorry for him and takes him to her house.
Seonghun invites Jadoo as well as Mimi and the baby to his house, and Jadoo and Seonghun become close.
But Yunseok gets jealous and picks a fight with Seonghun. Seonghun and Yunseok end up beating each other up…
