Boy Meets Maria

Both series have male main characters falling in love with non-gender-confirming characters. The topics surrounding those lovely characters are not for eveyone, sure, but I believe people can learn from them about how difficult life can be when you are not like how society wants you to be. Boy meets Maria is a single volume from Peyo while Fukakai [..] is 5 volumes long by a not very recommendable author, but please give it a try nonetheless.
