PKPD-267 Half-in-half-out girlfriend type, Meitan (20), Miku

I don't need a girlfriend, but I want to have lovey-dovey sex. I want to go on a romantic date, but I don't want to be tied down. It is difficult to find such a convenient relationship. And I definitely don't want to break the relationship with my niece like that. When will the day come when he starts dating Shigeru seriously? Or will there come a day when we won't meet? I don't know, but I seriously want to continue this ambiguous relationship with my half-girlfriend forever.
