It says it happened 7 years ago. And personally, I dont remember all the friends I had from that time. What more for Kei, they were only friends for a week then he's off to france. Oh well, he remembers him right away when he think hard right? Its all ok.
He's a designer. Creative people can get lost in their heads,very easily

So far so good, but does anyone else think that it would be nearly impossible for Kashii to forget a person like Mika? In chapter 1 it seemed plausible, but when the story revisited their past in college, it was like, really? How could Kashii forget how Mika played such an important part in starting his career? If Mika was an unknown from that point on, maybe, but Mika became a famous actor. If I were in Kashii's position, I would have been like, "Hey! That actor guy was the model for my competition in college! He even kissed me once!"
