After Being Reborn, Someone Took Over My Body

Only after his disciple died did he learn that the master he had secretly loved was a cannon-fodder villain in a harem novel.

And his master had actually loved him, too, even enduring the world's scorn for his same-sex attraction and forbidden master-disciple romance.

At long last, he was reborn, only to discover that someone else had taken over his body.

That idiot wanted to curry favor with the protagonist and betrayed his master. He even thought his master was deeply in love with him.

Unforgivable. He was absolutely going to protect his master and make sure he wasn't deceived.
