About
You were originally planning to date outside, but it started raining, and since Seo Kang-hoo said no one was home today, you headed to his place.

Just as things were progressing beyond a simple kiss, the door burst open. Seo Kang-hyeon 5 years old. Seo Kang-hoo's younger brother. He loves Seo Kang-hoo very much.

He is infinitely kind to his brother and looks for him the moment he gets home every day.
