It's Krystal's time of the month. She's currently being moody and y; getting annoyed at every single damn thing. The usual melodic sound of the birds chirping annoyed her beyond. The loud airplane that flew above her house irritated her. She craved for certain foods but was too lazy to actually go out and buy made her angry. She's basically behaving like her normal self except a ier version

She hates that every single women has to suffer and bleed every once a month. The terrible cramps they get, the unpredictable mood swings that others had to bare. It was just so unfair! But krystal accepted it as she can't do anything about it. The person who krystal felt sorry for was her boyfriend , the one and only, Kim Kai. 

Kai is the pride of Seoul high , an ambitious young man who achieved many things at such young age. He met krystal during their first year. It was love at first sight actually. He was chilling with his friends when a goddess walked through the door. With striking red hair, walking along side with sulli, she caught the attention of many other male there. Kai was one of the many who was mesmerized by her beauty. It was hard for him to get her attention as she had a cold personality, but kai was persistent. He kept trying and trying and finally after 7 months, she actually talked to him! Even though it was just a simple 'hi', it still made him feel special! It was a progress. He helped her with her bags, carried her books, and even did her assignment when she was tired. He didnt mind as long as he could be near her. His affections for her kept on growing stronger.  

 He knew he had to ask her to be his girlfriend. Kai asked her at the end of school when everyone was gone. He wanted it to be private and so he wouldnt embarrass himself if he ever got rejected. The moment came and he confessed like a real man, straightforward with no stuttering. Thats what he thought what had actually happened. It sounded more like "he-h-ey kr-kry-stal, umm i-i was w-wondering ummm, I forgot, ummm, s-sorry well i t-th-thought you know, maybe we c-could catch a umm a movie this weekend
