夏色十色 有意義な休暇の過ごし方

Today is July 23rd. It's the first day of summer vacation, and it's Sakurai Riichi's first day living alone for some time.

His parents are on a vacation to America and won't be back until September. He's been left behind because he's a student stuck taking entrance exams, but...

At best, he'll spend his last summer vacation in high school without anyone disturbing him!

What will Riichi get at the end of summer vacation?
