carrying Rihito's bags as usual,
but Rihito seems to have certain intentions...?
And that is───
To celebrate Ereki's birthday
with a surprise!

Rihito immediately starts thinking of various plans, but since he has no experience celebrating with surprises, he doesn't really know what would be good.

So, what should he do...?
Just then, Guest and Taro appear...?
