Can confirm the series only gets gayer with new chapters.
At the start, I thought subtext tag would make sense, but recently I think it'll be hard for the author not pushing it to full romance. Although, if you care about fish stuff, keep in mind that it'll focus less on the aquarium later on.
Pretty good so far, I always enjoy these 'literal who' x 'most popular girl in school' pairings. Only thing I'm worried about is the subtext part. Y'all says it get's gayer but there's always a chance that it'll get gayer but never actually become gay.
