As Kai lay Yuri's body in the infirmary, he sigh. Did I just slapped her? Aish what the hell am I thinking? he thought to himself as he groaned in frustation. "Oppa?" Yuri said as she rubbed her eyes. Yes! My plan actually worked! Well played Yuri, well played. Yuri thinks to herself as she keeps her innocent face. "Hm?" Kai looked up to Yuri. "do you brought me here oppa?" she said and she smiled. "ah..yes" kai said "hey, just rest and you will be fine. i am going to class right now, see ya" Kai said as he stand up but stops when yuri grab his wrist. "oppa, please stay here" yuri begged. Kai just sigh and turned his body "look, i have to go. or else...i...i'm going to missed the lesson" kai said as he avoid yuri's gaze. "since when you care about school?" yuri said as she cocked her eyebrows. "look yuri, i hav-" "oppa, i really like you, why can't you see it?" yuri said, her voice are trembling, there's a sincere in her eyes. "i never, confessed to anyone before. but for you...i make an exception, i broke my promise. when will you look up to me oppa? do you like someone else?" she asked to kai, she tighten her grip. kai just stood there, he's confused, he don't know how to react to her confession. "oppa...answer me" she said. "or else i'm not going to let you go" she said. Still no responses, I should've known this. yuri thought to herself as she sighs. "yah opp-" "yes there is" kai stopped yuri as he let go his hand from yuri's grip. "w-what?" she look to kai, widened her eyes. "yes, i like someone else" he said. "d-do i know...do i know her?" yuri said, she still can't believe what she just heard. "do i have to answer this? this is not your bussiness yuri" kai said as he walked out. Not my bussines? we...we were so close, why did he said that to me? He like someone else? i...i can't believe this. all this time i wait for him, he like someone else? why do you this to me oppa? ottoke? why did you changed? yuri said as her tears starts to roll down. she shook her head and she cover her ears and she cried harder

Yuri sat down on the bench and she cries as she looked at the paper in her hand, it's her first year in elementary school. "erm...why are you crying? gwenchana?" a boy with a wide eyes came to her. "ani, i am not fine...look" she said to the boy and she passed her test paper to him. "aigoo...you got F? this is really easy!" he said to her as he snapped his fingers. "so you're saying that i am stupid?" yuri looked at him and her lips are trembling. "omma will kill me if she see this..." she said as she starts to cry again. "y-yah! aniyo...i'm not saying that you're stupid! please stop crying! and by the way, we're in the same school. so how about this, let's study together, i will teach you this! and i can guarantee that you're gonna have an A on the next test!" he said as he shows yuri his sweetest smile. Yuri looked at him and a smile starts to form in her face "cincha?? jeongmalyo? kamsahamnida!" she thanked him as she starts to jumping up and down in excitement. "oh! I haven't got your name" he said as he tilt his head. "yuri, kwon yuri imnida" she said as she offered her hand. "Kim Jongin imnida~ but please, call me Kai. I didn't like it when someone call me jongin" he said as he took her hand and shake it. yuri just nodded and they get along with each other. they got in the same school since elementary until high school. 

Yuri cried even harder when she remembered her past, they're really close to each other since elementary school. They go in the same school from elementary until high school, but now...everything's changed. Kai changed. He's a kingka and he's really cold to girls, yuri tried so hard to be close to him, but kai found it annoying. A lot of boys, even kingka, chase yuri. but yuri didn't care about them, all she cares about is kai.

Yuri starts to cry even harder, she locked the door and she sat down behind the door. She sobs even harder as she hugged her knees. Modeun ge nae tasiradeo geurado gwaenchanhayo...ireon nar yongseohaejwoyo geudaer saranghan nal. Even though it could be all my fault, that’s ok. As long as you’re there. Please forgive me for being like this, forgive the person who loved you...
