Two high school male students, got transported to another world

MC turned into a beautiful girl despite being a boy , and his best friend who also transported with him got the job "hero". His best friend was handsome, the perfect guy with tall, athletic and smart. But his best friend have stoic/robot personality and did not talk much.

So mc registred herself as mage and begin journey with his best friend to defeat demon lord, one day a gang of bandit/thug try to kidnap mc to sell her as slave , they also say they want to have fun with her first, and mc best friend come and beat all the bandit.

MC then feels his heart throbbing and realized this is a sign of love... he then beat himself and say he was a male.

It is not Isekai bishoujo juniku ojisan , the story was pretty similiar to be honest , but in Isekai bishoujo juniku ojisan the mc was an office worker along with his childhood friend who also officer worker.
