Fuck this lol.
"I love you"
series ends
What a joke, why are most yuri series like this? It's a complete joke
Well tbf most romance series in general are like this, not just yuri. Unless it's extended by love triangle/harem "who is the MC gonna end up with???" nonsense, most romance series ends after the MC and love interest confess and get together.
It's super rare to see stories continue to explore the nitty gritty of staying in a relationship without padding out the series by doing things like focusing on side pairings (Anemone is in Heat) or other characters (Whispering You a Love Song). Or if they do still focus on the main pair, but it's mostly fluff compared to the drama of the pre-dating arc, it ends up feeling a bit dull and lackluster imo (Can't Defy the Lonely Girl). This is why How Do You Relationship is such a gem.
While I would have liked a few more chapters of Asahi and Hinako exploring couple life together, I couldn't see it being dragged for more than a volume at most. The main point of the story was about both Hinako and Asahi's character growth as people (Hinako learning to be more self accepting and Asahi learning to live a life that doesnt revolve around caring for her sister). They accomplished that fairly early on, so aside from adding 1 or 2 chapters before the confession so it didn't feel as rushed and a 1 or 2 chapters of fluffy couple life, the story it wanted to tell was done.
