"W-Who's that girl you k-keep talking about?! She's nobody, right?! R-Right?!"
"Ah...she's no one. Just this girl I met at...at a past life event."
"Past life event?! So you've been seeing this girl for more than just our current lives?!"
"Yeah...we knew each other back then."
"E-Eh?! You're hiding things from me! Tell me more! How did you two meet? What's her name?!"
"Oh uh...her name is Minami. We met when we were kids, I wanted to play basketball but she was into swimming so we'd always have these sports battles."
"S-Sports battles? M-Minami and you? T-That means you've known her for a long time!"
"Yeah...I guess you could say that."
"Y-Yeah, it's kind of obvious now that you mention it! So why haven't you told me about her sooner?! Did you hide her existence because you were embarrassed or something?"
"No...it's not like that. It's just...she was never really important."
"What?! W-Well, what about all the times you talked about her lately? It sounded like you were really close to her!
"Just...a few weeks ago we had an argument and she left without telling me where she was going."
"An argument and she left without saying anything? H-How could you let her leave like that?! You should've tried to find her, or at least called her to make sure she's okay!"
"Yeah...I should've done that."
"Y-You should've! Don't you care about her? Why are you being so irresponsible?!"
"Of course I care. That's why I'm so mad at myself."
"Mad at yourself?! You should be much more than mad at yourself! You should feel guilty for the rest of your life for letting her go like that!"
"W-Will you really feel guilty for the rest of your life? Or are you just saying that to appease me?"
"T-Try?! W-Why don't you do something more than just try?! Go out there and find her! Apologize to her for what you did! Make sure she's okay!"
"Alright...I'll go find her."
"G-Go on, go find her and make things right! But don't come back without her!"
"Hmph! You better not! Now get going! And don't you dare return without her!"
"G-Go! And make sure to apologize sincerely and genuinely! Show her that you really care about her!"
grabs a coat and heads towards the door "Wait! D-Don't forget to take your umbrella! You know how rainy it is outside!"
As my little sister rushes out the door to find Minami, she can't help but feel a mix of worry and jealousy. She's never had anyone besides her to worry about before, and the fact that she cares so much for this other girl makes her feel conflicted. She wants to be a good sibling and support her, but she also can't help but feel a twinge of jealousy and possessiveness. As she waits for her sister to return, she can't shake the feeling that she's losing her place in her sister's life.
Looking at phone "Huh? 8 text messages? All from the same number..."
bursts through the front door, breathless "D-Dutifulmuse! I found her! I found Minami! She's okay, she told me herself!"
"Oh? Where is she? Is she okay?"
"She's okay! She told me she's doing fine and that she didn't mean to leave like that. She was just upset from our argument."
"Y-Yeah, thank goodness she's okay! I was so worried!"
