Interest Stacks

manga where an idol and a fan have a chance meeting and become friends, lovers, or coworkers! titles will not be considered if the fan is not enough of a diehard or if they change allegiance to another idol: these fans have to be nigh religious about their idol worship! streamers or online personas may be considered as idols, provided that they sing or perform. novelists, actors, or celebrities of other kinds will not be considered; this is about penlights and ita bags, people!
