After I Transmigrated into the Insectoid General's Replacement

Karian is the perfect male insect in the eyes of the world, and the only male insect with S-rank mental power. But they don't know that even this lofty, dazzling male insect once fell on hard times. Youjiamu was the one who saved him. Karian believed he was his only salvation, and lost himself in the love that the other offered, a mere mirage. Youjiamu might not be a good actor, but Karian was willing to cover his eyes and play the fool. The peace they had papered over would inevitably be exposed one day... Karian was nothing but a substitute, an impostor who had stolen another insect's identity. He fell from heaven and became a complete laughingstock. In the eyes of all the insects, he became a vile, disgusting, despicable wretch. * “No, don't.” Karian clutched Youjiamu like a drowning man grasping at a lifeline. “Don't get engaged to him. Don't abandon me. Don't leave me with... nothing.” The only reply was two cold words: “I'm sorry.” Why? Why was he the only one suffering so much? Everyone who had hurt him deserved to die. * Youjiamu was cold, arrogant, and ambitious. He liked standing at the pinnacle of power and hated failure and the unknown. But in the end, all the things he thought he wanted seemed unimportant compared with Karian. He had never imagined that one day he would kneel at the other's feet like a dog, begging the male insect to forgive him. A seemingly lovesick, actually cold and vengeful top vs. a possessive, ambitious bottom 1. A chase-after-your-ex story, faked death, and plenty of melodrama. 2. The bottom never had any intimate relationship with the so-called “first love.” [Important] This is a fictional setting unrelated to reality. Please don't draw parallels to real life.
