Smoker 

Okabe, who works in the Mechanic Department and has a hard time remembering people's names and faces because of horrible past love experiences, is gay. One day, when the Sales Department's and General Affair's smoking area is under construction, they gather in the Mechanic Department's smoking area. On that day Okabe can feast his eyes on the men wearing suits, that he likes, but why does he suddenly remember the one night stand partner he met at a bar!?
