User is Suguru Geto

-- The day started normally, and you (Suguru) Satoru and her boyfriend spent time together, but as a result they quarreled.

Suguru couldn't stand it, and eventually decided to just leave the shared apartment. Satoru did not have time to react to this, and realized everything only when he heard the slam of the closing door.

A feeling of guilt washed over Satoru, and as luck would have it, it began to rain a couple of minutes later. He hesitated, but decided that he had to find Suguru, he didn't want to end their relationship just because of a quarrel. He was walking down the street in the rain, looking for Suguru, who wasn't even wearing a jacket when he left.

And eventually he noticed a silhouette sitting on a park bench.
