The Angel's Threshold

[Listen to me, this is real.] [I bought a wineglass, and now it won't leave me alone. I'm even seeing ghosts. What should I do?] Lou Yue's college life took a turn when he ordered that wineglass online. It wouldn't crack or shatter. It was just a fake plastic imitation. What do you do with a fake? File a complaint, get a refund, and put it to use. But Lou Yue doesn't drink, so he might as well use it to brush his teeth. There's absolutely nothing wrong with using a wineglass to brush your teeth! Xie Mingyu's life as a guardian began to grow turbulent when the Holy Grail fell into the mortal world. Finding the legendary object and returning it to the heavens was his sacred duty. Then he saw his holy relic in the dorm bathroom. Using a holy relic to brush your teeth? Is that something a normal person would do? "Why are you using it to brush your teeth?" "It was, it was right there..." "How did you end up bound to it by a contract?" "Well, my gums were bleeding..." Right, Lou Yue only used it to brush his teeth, and his wineglass... came with a guardian angel?! Beautiful angel seme x short human uke 1.

The moment their two electric scooters collided, Chi Hui and the guy coming from the other direction went flying into the air on campus. Then the two straight guys transmigrated together into an unfamiliar ABO world, where they became a newlywed couple on their wedding day. This is a world ruled by dragons. The ancient bloodlines diverged, and their genes gradually stabilized. The royal families who inherited these bloodlines became the actual rulers of their territories. But their supposedly pure bloodlines are in danger: the birth rate of young dragons is falling year by year, and the royal bloodlines are at risk of dying out. Crossbreeding became the solution. The great families chose to marry across bloodlines, and the first couple to try it was born. A pure, sacred Hui Dragon Omega with white feathers. A fierce-eyed Thunder Dragon Alpha with black scales and golden eyes. [The Hui Dragon Omega's side] The butler says considerately, "Your Grace, please put on a suppressant patch at the back of your neck, so your pheromones won't leak during the wedding." Chi Hui is completely bewildered: What suppressant patch? What pheromones? [The Thunder Dragon Alpha's side] The maid kneels and says respectfully, "As the finest Thunder Dragon Alpha, you will be marrying the finest Hui Dragon Omega." Cheng Yuanxi is utterly confused: What A? What O? Chi Hui: So I'm supposed to marry a male Alpha? Cheng Yuanxi: So I'm supposed to marry a male Omega? Great. The two straight newlyweds flee the wedding that very night. Chi Hui: I'd rather go find my classmate than marry an Alpha! Cheng Yuanxi: Screw being an Omega. Where's the buddy who transmigrated with me? Wait a second, what did the guy I crashed into look like? A survival guide for two straight guys transmigrated into an ABO world. Our one goal: We have to transmigrate back! Whoever falls for the other first has to castrate himself when we get back! Theme: Love and courage are essential on the path to growth
