A traditional Japanese wedding! Marin calling her boyfriend and now husband, Wakana-kun! Married adult romance (for one chapter only...)! Adult Marin with the wedding ring on page 7! Adult Wakana with his wedding ring on page 13!
From "just started dating" straight to "young married couple" - boy, this romance rocketed straight to the moon. Too bad no kids for them (yet?), but it feels good to know these highschool sweethearts ended up together and are still going strong. Marin's love for Wakana sure is rock-solid, hope she's still a gyaru even after becoming an adult. Adult gyarus are a rare treasure...
I really like this time skip ending. Do I want more from before this? Sure, but I'll take what I can get. This has been running for seven years, huh. Now I doubt the possibility of a sequel since sensei might want to move on, but if one is possible, they'd have to start it as adults, and maybe feature their possible kid as a main character of their own romcom. Or a family doing cosplay as a hobby, that might work too.
Anyway, I really hope the anime season 2 can reach this point and have an ending. Finally over, it was nice while it lasted.
