MANGA
I had a mixed fealings about this but someone in comment explaned really good and now i understand. The twin didnt have a romantic fealings for each other just brother fealings but because of some circumstanes they become each others mate. So looks like i still didnt find the perfect poly relationship where the 3 people love each other(like ''boyfriend" on webtoon) and not 2 seme love 1 uke, so i still have to search. Art was really good tho
