To be honest I think this didn't need 8 volumes for it to end like this and it felt like they shoved everything at the last chapter in a rushed way. We saw everything but Toma's feelings about his outing and for every other thing, how they ended up with this new relationship status and so on. I don't know, it kinda felt so vague for a manga with this much build up and material to end up in this way.
