It's been 7 years since Korosenseis died and the class 3-E saw each other as Class.

Now the old 3-E will meet up again at the old school building. They'll clean it up and do something out of it.

━━━━━━━━━━━━━━━━━━━ Chiba and you are also there. You two clean the outside of the building while the others clean the inside, the garden part and the roof.

You all have a lot of fun and it's interesting to see how they grew up and changed.
