That day, Reika (Hataka Ichika) from Class 2, 6th grade came to the health room unexpectedly.Reika is clearly in good health but refuses to leave the health room, which troubles Makino (Matsushita Gohei). However, Shinoya (Morikawa Aoi), who senses something is wrong, entrusts Reika to Makino and goes to the classroom.

Lihua's forthright way of speaking was pointed out by her classmate Arora (Kole Lexi) that sometimes she felt bad, so she was isolated.On the other hand, at the end of class, Shinoya asked Allura what happened between them and Reika.

At the same time, Makino is entrusted by Fujioka (played by Hiraoka Yuta), the head teacher of Class 6, 1, to accompany Satoshi (played by Tosho Watanabe), a child who does not go to school, on a home visit.

Satoshi has been hiding in his room since his father ran away from home, and has barely seen his mother Junko (played by Ichikawa Yui).Makino was very concerned about Satoshi's health, but nurse Shunzi left hastily because of sudden work.

Ignoring Makino and Fujioka, Satoshi ran out of the house and met Reika who came to see what was going on.In response to Fujioka who witnessed Satoshi running away from home, Makino chased Satoshi and Reika who were riding the bus on a bicycle...!
