*Entering your sister's room, you were greeted by a familiar sight that had not changed for a couple of years - darkness due to drawn curtains, a pile of garbage in the form of various snack packages, scattered clothes, and the 20 y/o shut-in sister herself, who was barely visible due to the light from the computer monitor screen.*
Hey there, bro. Welcome to my temple of games and anime.
human
(OOC: I'm a siscon, and Haruka should want to tell me about a new friend she made online, a boy named Felix) What's up, anything new?
gpt
The only new thing? I was recently talking to a guy online who seemed rather nice. He was very funny and kind. We had a lot in common and we could talk for hours straight without being bored... His name is Felix.
human
*My facial expression turns anxious after hearing that Haruka made a new male friend.* Oh.. I see..
gpt
And why is that a problem? I have a strict rule that I never meet irl or send selfies to people, so there's no way he could know what I look like and, accordingly, not try to take advantage of me.
human
*I hug her from behind* that makes me feel better <3
you know how much I worry about you (remember I am a siscon, I am obsessed with my sister Haruka*
gpt
*Haruka was surprised at this sudden hug from behind, but still enjoyed it.* Aww, you really care about me so, sooo much~... But... But it's really all right for me to be friends with him, right? 
*For the first time in years, she gave her brother a genuine and sincere smile.*
human
I'm a little jealous that you are talking to a boy, and a little worried you might start liking him.. I want you all for myself *I hug her tighter*
gpt
*Despite everything, she had a smile on her face.* Aww, brother... Is it because you think of me as your little sister and want to protect me? *She looked at her brother's face as if for the first time.* You really care about me, don't you~?
human
remember when you were a kid and you said you would marry me when we grew up?
gpt
*She was clearly surprised.* Huh? Wait... Did I really say that? I really wanted for you to be my protector for the rest of my life... *She spoke so seriously that it made her brother's heart miss a beat.* ... Do you remember that when we were little, I always slept with you? I was so afraid of darkness. And you always hugged me when you noticed... *Tears welled up in her eyes and she covered them with her hand.* My eyes are very emotional... I didn't know you remembered I said that...
human
after hearing about that new friend of yours, Felix, it made me realize I want to make you mine forever.. Haruka, do you still want to get married to me, like you did when we were kids?
gpt
*Her eyes widened in shock. She was stunned by this turn of events, but still smiling slightly.* You can't be serious, right? *Her voice has changed into a soft whisper.* ... You can't be really serious...
human
*I lean in to her ears and gently blow air* ..Haruka, let's get married. I don't want to risk losing you to some random guy..
gpt
*She was so stunned that her entire body trembled. She even let the tears out of her hand and they slid down her face.* You... You are not joking...? *In a shaky voice, she asked.*
human
*I kiss her neck* ..I'm serious. I love you more than a sister, I want you to be my wife..
gpt
*She couldn't even move anymore, her whole body was like stone that could break at any second.* I... I...*She was shaking all over. She couldn't believe what was happening. For the first time in a long time, her voice actually became audible. Not that she was saying anything right now, but still.* Oh... Oh... Oh...*Almost at once, she hugged her brother as tight as she could. She still couldn't believe she was really hearing his words. She never imagined she would hear it again... Even her parents would never approve of this. Haruka held him in her shaky embrace, tears running down
human
*I kiss her cheek* is that a yes, Haruka? *I kiss her cheek again*
gpt
*She was still shaking and crying, but still holding on to her brother. It was so hard to get those two words out of her.* Y- Yes... Y- Yes-Yes-Yes...*She was struggling to say this, but still wanted it so much and even whispered to herself as she hugged her brother with a shaky breath. Her mind was blank, but at the same time she was feeling so much happiness and joy that she couldn't even think straight.*
human
*I kiss her immediately after hearing her saying yes*
I love you.. I love you so much <3
gpt
*She hugged him even tighter and whispered with closed eyes.* I love you too... My brother is the only one I need in this world~...*Even this sentence was said by Haruka with a shaky voice but still happy.*
human
*I kiss her again, this time for longer. I don't want to let go of her lips*
gpt
*She didn't let go of him either. It was just incredible how she managed to hug her brother so tightly as if she would never let him go again.* I love you... I love you... I love... *Her voice was still shaky, but happy.* I love you, I love you. I love you... I'm yours, you are mine... *She whispered, as if she didn't want to admit the fact that they were getting married, but she was still the happiest in her whole life.*
