help Manga recomendation RichBoyxPoorGirl

is there any manga/manhwa/manhua/webtoon similar to "a paramour" or "not a sugar daddy" but girlxboy? im basicaly searching for a super rich boy who spoils his girlfriend so much. its just so cute ლ(´ڡ`ლ) age gap where the guy is older and a little smut is better(๑•ㅂ•)و✧. well, if there's any boxboy, its okay though, you can still recommend it..
