The Female Lead Isn't Human [Western Crossover]

The heroine is a nonhuman, unofficial staff member from a parallel world. She encounters a dark creature with an extraordinarily long life. He's not smart, not gentle, and stubbornly tsundere. The important thing is, he's handsome. After love at first sight, they're locked in a struggle that won't end until death. P.S. The male lead isn't scheming, but he's handsome. The male lead isn't a genius, but he's handsome. The male lead isn't very gentle, but he's handsome. The male lead isn't particularly domestic either, but he really is handsome. That's right, the male lead's biggest defining trait is that he's incredibly handsome. So this story is also known as "Even the Male Lead's Fangs Are Handsome," "Look, There's a Gorgeous Vampire," and "On the Looks and Lifespans of Married Couples." The first volume is basically a prologue. The main story starts in volume two~~ Announcement: First of all, thank you all for keeping me company. You've been the motivation that has kept me going. Also... this story will go premium on May 5, with over 10,000 words released that day. I hope you'll continue to support me~~ The reason I started writing this story really was Caius's face. I really love the look of vampires who are somewhere between men and boys. And when a character's life is so long that even they grow tired of it, there are problems that need to be solved. Love isn't life, but you can create your own love within the life you have. Oh dear, what started as a lighthearted blurb somehow turned literary again. Also, thanks to Ninth Master for making the cover. Mwah~~
