As for tips on yours, it's not a bad start, but I would recommend putting periods and/or other punctuation at the end of the bully's lines. Other than that there isn't too much to critique yet.
As for my series—
Demon House - Well the focus of the story isn't that many of the characters are LGBT+, but there is a side crush/romance between two guys, and later there will be a crush situation between two girls. Um, characters range from pan, bi, gay, lesbian, ace, and trans.
Heavy Horns - A not so romantic romance between a bi guy and a gay guy. There are also lesbians whom I'd love to expound upon more in this story or another but they basically have a fairy tale romance with no drama at all. sighs over them
Erie Waters (completed)- Half drama, half romance (I guess), there are only four recurring characters in this and they couple off nicely to mlm and wlw, basically.
At Ease (completed) - A one-shot companion piece sort of to Erie Waters, mlm.
Sarota Springs - My newest series that will start posting sometime in December, I'd say the protagonist is demisexual. His best friend is lesbian, happily married, and there's a pan character and a gay guy. No romance really in this one.
