So I have not played Morenatsu (and don't plan to anytime soon) but I have watched their walkthroughs on youtube. My two favorite characters are both Tatsuki and Juuichi. I started drawing them as how they were in the game but decided to draw how they would look four years older. Tatsuki has longer hair, a goatee, and more muscles. Juuichi has a mustache, more head hair with a curl, and a strong belly and muscles. Their personality don't really differ from their youth.
