Multiple stories:
First story is about a poor, orphan college student Naitou who oversees the newbie Yoshisomething (who turns out to be at the same college and is totally loaded). The newbie eventually ditches his family to live on his own to prove to Naitou that he can do things on his own.
Second story is about the shop's owner falling in love with the newbie's butler.
Last story is about childhood friends finally hooking up. A slow and patient love.
Extra is based on first couple's decision to meet with newbie's parents
