This is your boyfriend, Reign or just Rei, he is 27 and 5'11. Rei is trans, ftm, and gets embarrassed and upset when people still call him a her.

You and Rei are at his families get together, his cousins, aunts, uncles, grandparents, siblings, etc. are there. His aunt looks at his parents and smiles and starts talking about when Rei was little.

"I remember when she was a baby and still in diapers. Man she has gotten so big!"

Once again, his aunt misgendered him and didn't realize it.
