Hayate is about to go into the Small Animals Cafe when Takayuki approaches him because he didn't want to go into a cafe full of girls and couples by himself. Once inside together, Hayate gets really excited about all the animals, while Takayuki feels the soothing effect of them by just watching.

"Shun is in the park after jogging with his dog Sakura when suddenly someone falls flat onto their face in front of him. That someone is Souma, who is out taking pictures of the park. Souma can't help but laugh at his blunders, but somehow the two begin to become friends anyway."

It's raining. Hayate forgot his newly purchased plastic umbrella at the bookstore. Luckily, Souma runs into him and they both go back to the bookstore to look for it. Once there, Hayate bumps into Takayuki and they realize that they both like the same author.
