Yes. The Nagatoro manga reached its end, giving fans a sense of closure. There might be some mixed feelings among readers, but the final chapters tied up loose ends.
I'm not sure if 'the senpai a seinfeld visual novel' is popular. Since I haven't heard much about it, it may not be widely known or it could be a relatively new release that hasn't gained a large following yet.
It could be about the relationship between the protagonist and their senpai. Maybe it involves the daily interactions, the growth of their bond, and some emotional experiences like friendship or a budding romance.
