Kaguya may have crossed this line recently, but true people of culture know that the main couple in Do Chokkyuu Kareshi x Kanojo are the true champs of getting to the finish line
They aren’t doing it next chapter when they try to do it either both sisters come and cock block or the bitch that owns the place to give them food or some other stuff
I call it, this is a big bait, even if she says sex, it's going to be a joke for her, i bet it. If for some miracle there is not cockblock and they do it... Wow.
