Highest rank : #1 in AyatoXYui "Let's get married." Words that brought happiness to one's ears. "Really? Another human girl is going to live with us?" "This is my younger sister, Amaya" One after another. "I am Seiji Komori, Yui and Amaya's father." But some were disguised as happiness. "No way is my daughter going to marry a Vampire." Where there's happiness, there's sadness too. "I just want Yui to be happy." However, there's a lot more to come. "I wanted you to meet them. This is the Tsukino family." "They have come here for your and Naoki's engagement." With a little bit of humor "LET'S GO WEDDING SHOPPING!!!" Comes lots of horror as well. "I will...kill them." "I think you forgot sweetie, I can't die." "Hey, is this his girlfriend?" Many secrets, yet to be revealed. Another, who wants to destroy everyone's happiness. "I guess, I should go and wish Naoki for his engagement." There's also a second story to see "Could it be... that I've fallen for Subaru?" Many more people to meet "Who is Rin?" Will there be blood shed? "This is the end." "YUI!!!" Or Will there be a happy ending? "I love you . . . Ayato Sakamaki." "I love you too . . . Yui Sakamaki." "Suffering In Love"

Tsukasa and Rui both hate each other for their own reasons, but a little accident has been slowly bringing them closer, eventually making them realise their feelings for each other
