​​​​3RD POV ~

The door's open suddenly make their three shocked especially you. At the door frame , all student from E-class and Irina standing there with trying to catch up they breath. You still stiff in the position, your hand still at his face with his son grabbed your hand off from the adult face. For a few minute with silent killer~ you let go Kuhou cheeks. You sigh and pretending what did you do just a moment ago.

"What are you doing here?" With cold voice. They all shock, your tones now completely different from when you at the class. "(Y/-" He begins. "ANSWER ME!!" you cut him with a yell. Irina looked terrified... that's all you thought just now when see Irina face. You just worries about Irina including tadaomi and Tako cause their are your friend when you started and half way became assassin.

You snapped from your thought when someone start to talking. "(Y/N) I'm sorry. Please, don't go.. don't leave me again!! I don't wanna lost you again!!" Nagisa beg to you. "No. I warned you there but what you did? you won't listened and told me too apologied to her, isn't?" You questions him. Make him guilty. ​​​​​"So, what your reason came here?" Kuhou ask like nothing happens.

"Duh, exchange me to other countries. I don't want to be anymore and inform me, okey?" You say. "Hmm." He raise eyebrows. "Can't take it?" With look poker face then Kuhou smirk to you. Well.. ​​​​​​That's just a lies.. What just you said to kuhou is a secret language between you two. Weird, huh? *laugh* I will translate it for you... If you want.. Nah~ I'm kidding~ I'll tell you....

-What happens?- -Don't want to talk about it. Just, drop me out from this school. I'll be in Japan for a weeks or month, not sure and always please inform me about my bother, okey?- -Why?- -Don't pretending you don't know.- He's smirk with's mean -Okey.- Hahaha.. I'm crazy. "No.. Don't do this (Y/N)." Your brother run and hug you with a little tear at his eyes. "Let me go, Nagisa." You say.

Your head looked down so no one can see your eyes. Nagisa tense up when you call him by his name and not the horrific as your brother. "NO!! Please, (Y/N)." You could felt your clothes a little wet.. Nagisa now crying at your shoulder. You heart felt hurt, guilty.. ​​​​​All your life is a fake from the started you go to USA. You doesn't want to leave your brother but you didn't want him got hurt cause your dangerous missions.

​​​​​​You discharge yourself for him then run to the near one of the window that open so you can get out from there. You jump out, didn't thinks about you can get hurt. You pick to used window cause all the E-class is hinder the door. Making you trapped in the middle of center room with your brother hugged, cried and the other stiffed at there spotted. Last things you said before jumped out through the window is..

Goodbye.. With sad expression. Nagisa fall to the floor still crying.  Why (Y/N)? Why'd you must leave me again? He thought. Irina at the door in the same situation like Nagisa, crying. Karma and another student from E-class try to comfort him and Irina. I just want you to be safe, Nii-chan. You thought while ran away to no way you think to go.

NAGISA POV~

I fall to my knees, cried at the floor when (Y/N) gone. I can't think anything, my mind just going blank. "That is your fault..." I heard, looked up who owner the voice. Principal? -Asano Gakuhou- My fault? Me? More tear in my eyes. "You-" Karma start to yell to say something. He stop typing at his computer and sit at the side his chair, looked down at me at the floor. "(Y/N) was gone how..."

He sigh. "She didn't like someone force her, did you know? She don't have many friend, alone for 7 years at USA by herself." He pause and close his eyes. "3 years ago, she really happy when I told here that you started school in here. She always called me to asked me to informed her about you from time to time to know your conditions and what did you do at school."

I see he smile a little but soon turn to frowns. "Always asking me anything about you who never remembered her or try to contact her." He said with dark voice but lower. S-she do that? Always asking about m-me? ​​​​​"Hiding her illness from everyone. Hide it with fake smile that she always give to everyone near her include you." He said more louder. "I-illness?" I stutter in shock. "Yes!!!" He yell, angry.

Why did she never told me? I was her brother... "You.... You don't know, do you? You always happy with your friend but didn't know about her illness. When she came here, talked with all your friend. You think she happy? Did you know she crying all night?" I didn't know.. Why? "Sometimes... I was thinking" He say with his usual voice. "You was never be a real brother to her or.." He glare at me..

"You are not EVEN her real brother because you know nothing about her.." The words snap me. "I-I'm her real bro-brother.." I stuttering while thinking. Or I'm not? "You should thinking all back what have you done to her." He sigh. "I'll tell you this but she didn't want you or the other to know without her permission but... I do this for her happiness, I'll tell you." He look at the others..

Gakushuu and other student from E-class including the teacher can go back to class. All of you, dismiss except Nagisa. Leave him here." He say, serious. After they left me in the office alone with principal. He begin to speak first after let out a heavy sigh. "(Y/N)... She have mental problems actually.. She went to USA to learned how to controlled her emotions and........"

*TIME SKIP*

I go back to old campus but all the words that out from principal mouth. My heart feel so painful and guilty.. What have I done? She always felt distressed about her pain.  The words replay in my mind. I sigh, walked slowly to old campus.
