u could try this list, if it’s not what u look for u could search ur specifics in the search in that link
also u could try https://www.mangago.me/read-manga/please_take_care_of_me_in_this_life_as_well/ i’m not sure if it fits the same type of “popular” u look for but it’s interesting and not like regular shoujo (well it’s a manhwa but yea)
and i always rec , ao haru ride lol it’s my favorite shoujo
hope this helps
so i just know some shojou that is normal fl x popular ml but is there any Popular fl x popular ml or popular fl x introverted(or normal) ml? looking for mangas but fine with manhwa/huas too. (also if u gonna rec seasons of blossom i already read that) thanks
