Don't Fall in Love with an Athletic Delinquent

1.

First off.

After jokingly saying, "Let's get together," she got an equally joking reply: "Oh, sure. Let's get together, then." And just like that, the two of them became a couple.

It seems her childhood friend is very athletic. He joined the baseball team and became the starting catcher before long. His practices keep him so busy that it takes ages for him to reply to her LINE messages.

Kaori doesn't feel lonely about it.

After her fellow rookies scolded him, "You popular types! Treat your girlfriend properly, damn it! Actually, forget it! Hand me your phone! I'll reply for you!"

The messages stayed unread for ages. When he finally got a reply, all she said was, "Another day spent doing my best to save the world!"

"Save the world?"

"Yeah... Actually, have you ever seen an anomaly?"

"No."

"You're welcome."

"???"
