A Straight Man Turns into an Omega and Gets Marked by the Insectoids

[Growth arc + adored by everyone + all admirers have one-sided crushes]

Lu Sheng is a straight man who transmigrates into an ABO world. To make matters worse, he presents as an Omega.

He really doesn't want to be with a man!

So he grits his teeth and pretends to be a Beta.

But his face grows more and more delicate, and his waist increasingly slender. No matter how well he pretends, his childhood friend notices something is off.

His childhood friend viciously drugs him. To protect his virtue, Lu Sheng stumbles off into the wilderness to escape.

In his haze, he feels cold, jointed limbs coil around him, while sharp claws slide downward.

His heat happens to hit, and Lu Sheng, his face flushed, wraps his arms around the “thing” behind him.

When he comes to, Lu Sheng is dumbfounded.

Was that just like getting bitten by a dog?!

Just as he manages to escape by disguising himself as a Beta and diligently prepares to study his way to a better life, his once peaceful existence is shattered again. His Omega identity is exposed, and his formerly kind and friendly companions seem to have become different people...

Even the monster comes looking for him, following his scent...
