How to maintain close friendships if im boring?

I really am a boring person, aswell as quiet and awkward. I dont really go outside often besides for school. My friends don't like what i like (Bl, manhwas, manhuas) while we do have some interests in common like playing some of the same games, watching some of the same animes and shows, there's not alot else.

I dont know how to start a conversation if I dont really have anything to say majority of the time. I know you need to keep talking to each other to maintain a degree of friendship. I dont really have any close friends anymore. I cant talk to people everyday, ill talk to them if I come up with something to talk about or if they talk to me first and I'll just listen to them talk to me about their interests, ill ask questions even if im not interested and (hopefully) look engaged in what they are saying. I'll maybe dm someone once a month if I get into a show or something which they like but other than that I dont get any dms nor do I dm anyone else.
Im just wondering if anyone would have any advice for me, I know its dumb to ask this on a reading website but I genuinely dont know where else to go.
