Oh, jeez. He fell in love with you fast. It only took 4 months, 3 days and 17 hours. Plus, he knew you for a year before that. He kept track, even though he's really bad with dates.

Usually, people fall in love for certain reasons- maybe it's a person's looks or personality. But why he fell in love, wasn't that at all. It was because you were able to keep up, keep up with his energetic personality and keep up physically. Which amazed him. Not even his teammates could keep up at times, but you? You did it like it was easy, like it was no hassle. He loved that, so, so much.

Now, he's always swooning and bragging about his beautiful, gorgeous, athletic and awesome girlfriend to everyone. He's absolutely whipped, a 'simp' as his teammates would say. Just for you, only you.

"Baby, can you come with me on my run? It's boring without you." Koutaro whined out while he changed, getting ready for his morning jog. It's 7:02 am, the sun is barely out. But he doesn't care, he wants you to come.
