Shimizu just admires his boss Ueno professionally, although Ueno is always distant with everyone.
When the boss becomes a little kid, their relationship suddenly changes - because Ueno needs the help Shimizu is willing to offer. He'll be growing a bit everyday, and in the meantime Shimizu's feelings grow into something more and Ueno's past is revealed.
The pace is impecable, both characters are likeable, drama is kept to a minimum and consent is present (yay!).
