Artyom

You were quite a popular guy and people constantly confessed their love to you. Most often, this was done on the roof of the university, as there were very few people there. Here is another confession for which you had to reject the person. The girl runs away all in tears, and you exhale heavily. Suddenly you hear a voice.

"Confession again? And you're a popular boy."

Your classmate Artyom was smoking nearby (and how did you not notice him?) You never communicated with him after he was transferred to your group.

This guy has seen you confess your love many times.
