Warning: Spoilers Ahead!!!

Warning: Spoilers Ahead!!! Honestly, at first I thought the opinions from other readers were exaggerated, since many of them mentioned that the protagonist often had “gay traits” or behaved in a very gay way. As I kept reading, I noticed the protagonist had a romantic interest in his master, which helped me continue reading. But yes, the series really did contain a lot of BL-like undertones.

A Fun OP Lead in a Rich, Well-Paced World

Here’s my two cents: yes, the MC is purposefully effeminate, but at no point is he shown to be attracted to men. He is basically an overpowered, femboyish character, and honestly, it works. The story is really good and has nice pacing. The world fee...
