The main couple in http://www.mangago.me/read-manga/card_captor_sakura/ is straight but there's a good amount of LGBTQ+ characters including the ML. The ML was a love rival of the MC as they both were into Yukito (whos also queer).
http://www.mangago.me/read-manga/kami_sama_no_ekohiiki/ is about two guys (its shoujo btw) and they explore romantic feelings that are not sexual. Another work by the same author http://www.mangago.me/read-manga/usotsuki_lily/ also has a lot of LGBTQ+ presence. This author makes truly groundbreaking stories that don't fit into a specific genre.
Hiii are there any good stories where there are different LGBTQ+ troupes? Preferably like, there are gay and leasbian main couples? Idk, I just want to see stories like that ٩(๑❛ᴗ❛๑)۶
