The MC has the good fortune to transmigrate into an insect world where the male-to-female ratio is wildly unbalanced and the class divide is extreme. Just as he is celebrating having become a male insect—meaning he will not have to marry some unknown insect gentleman as his eighteenth concubine—he discovers that he runs into a lovesick female insect while eating, a stalker while walking, a peeping tom when he gets home, and even kidnappers when he is simply minding his own business...

After narrowly escaping death, the furious MC reports the crime. The authorities assign him a bodyguard: a violent female insect who was discharged from the military after killing a male insect.

The female-insect bodyguard drives away every female insect lusting after him...

—and then starts lusting after this male insect himself.

The MC is rational, gentle, and calm, with a few harmless little kinks.

The love interest is handsome, powerful, and tragically burdened—and unexpectedly caters to the MC's little kinks.

MC: Weren't you supposed to be hard to win over?

Love interest: ...I won myself over.

1v1. They are each other's one and only in every sense.

A powerhouse pairing: the MC is physically frail but exceptionally shrewd; the love interest is physically formidable and no less calculating.

There is extensive original worldbuilding; this is not a story about gender equality.

In this setting, male and female insects look almost identical. Male insects are not necessarily shorter than female insects; personalities and body types vary. Overall, female insects far surpass male insects in physical abilities such as strength and speed.

Some female insects can undergo insectification. Picture a steel alien over two meters tall—but please do not imagine a giant bug.
