Anybody else kinda feel like this is reminiscient of Tamen de Gushi?
Um, not really at all? Maybe the tiniest bit in the character designs, but Sun Jing is a boisterous slacker tomboy who aggressively pursues Qiu Tong, who isn’t a gyaru, but a rather shy high achiever.
Where do you see the similarities?
High school romantic comedy webcomic about two girls, one cool one girly, discovering their sexuality, punctuating the current drama with fluffy hops forward on the timeline to reassure the reader that "Yeah, don't freak out, they're totally gonna end up together, they're just not there yet."
I think in that case the author started with the spot illos of the two of them obviously together (I especially recall a slinky bar scene with the pair up close and personal) before launching into the extended “will they or won’t they?” getting-together narrative.
So those forecasting scenes were less sops to the reader about where the story was going than the originary visuals of the character designs. (There was at least a flash-forward Christmas scene of the two of them living together, but that happened after the two of them became a couple in the main narrative, IIRC.)
