Response to v day text

This is dumb but hahah I’ve been talking to someone and I’ve never dated anyone before this is all new to me. He hasn’t officially asked me to be his girl since we can barely see each other because of this whole covid thing🙄 praying it’s over soon 🤞 if he says happy valentines or anything like that how should I reply? I don’t really know what to say. Should I just say thanks?
