On the occasion of my brother's wedding, I returned to my hometown to meet the family of his soon-to-be wife. Unexpectedly, the future sister-in-law turned out to be my first love from high school.

After the meeting, I went to my room and got lost in thought. At that moment, she suddenly appeared, reminding me of our unfinished youthful memories.
