His Constitution Is Different [GB]

[ABO] [Vampires]

In the year 4563 of the Star Calendar, the world was unified. To dilute the overly dominant ABO genes and ease the effects of their special periods, the last vampire on the Western Continent was incorporated into the ABO world along with other primitive species.

To help them quickly assimilate into society, the Federation government arranged blind dates based on genetic compatibility.

A month after receiving the notice, the female lead finally found time to go on hers.

The night before, her mother had told her to do a background check. She forgot.

The night before that, her father had asked her to bring some of the family's desserts. She forgot.

All the female lead remembered was that she had a blind date, so she showed up empty-handed.

The male lead arrived hungry and ate a mouthful of flavorless food while still hungry. The remnants of his vampire ancestral memories told him he needed to drink blood.

So he asked, "Could I have some of your blood?"

The female lead, who hadn't done a background check at all, replied, "Sure."

At their second blind date, her mother asked how the background check had gone.

The female lead, who still hadn't done a background check, said, "Um... he likes drinking blood?"

Her mother thought it over and sprayed her with garlic-scented perfume, saying, "Drinking blood without a little garlic flavor is half the fun."

As soon as they sat down, the male lead covered his mouth and bent over. "Ugh."

Someone passing by casually remarked, "Are you pregnant?"

The male lead thought about it and decided that made sense. So I am pregnant.

The female lead, who hadn't done a background check at all, said, "So you are pregnant."

There was no need for any more blind dates. She officially exchanged contact details with him, and when her boss called, she found a moment to tell the male lead, "Go home and wait for the wedding announcement."

Sometimes the male lead would wonder, "Why do I get pregnant when I drink blood?"

The female lead, who never had time to do a background check, found a moment to answer, "Everyone's constitution is different."

The male lead nodded, rubbed his stomach, and dry-heaved a few more times, with the faint smell of garlic lingering in the air.
