Slow Morning

Natsuo, now in his third year at an advertising agency, spends his days constantly swamped with work in sales. One evening, fed up with the noise coming from next door, he impulsively bangs on the wall. But when his neighbor comes over to apologize, Natsuo is stunned to find it's none other than Issei—his best friend from high school! Issei had confessed his feelings to him at their graduation ceremony, yet Natsuo had been unable to tell him that he felt the same way. Now, six years later, those old regrets and dormant romantic feelings come rushing back. Natsuo finds himself unexpectedly flustered by their reunion, but Issei acts as if that confession never happened at all—treating him simply as a friend..?!
