“How many times?”
“eh?”
“How many times have you kissed Akamine-sensei? One hundred? Two hundred?”
“I don’t know. I didn’t count
”
“Hmm. So you’ve kissed her countless times. Did you kiss her more than me?”
“Well, come on? I think it’s about the same, but
”
Kohaku smiles

I’m begging you, please put on a gentler smile like you always do

I got to know a new side of my ex-girlfriend, and learning that had me freaked out. The angry face is kind of cute, though.
“Then kiss me again.”
“Waa~, I understand!”
I immediately close Kohaku’s lips with mine.
“
Is it okay with this?”
When I asked timidly, Kohaku smiled satisfactorily.
Was good
 It seems that I was able to improve her mood back.
“With this means, I have become the one with more kisses, right?”
“Yes, right, absolutely, absolutely right!”
I don’t know if it’s true or not, but for now, all I could do is just say ‘yes’ here.
When I affirmed, Kohaku again requested seductively,
“Touma-kun, kiss me indefinitely.”
That’s when. Suddenly my mobile ringtone sounded. As I pick up and look at the called ID, I get startled.
“Kohaku, you’re in trouble! I got a call from Shirasawa-san!”
“Huh? From Mashiro-chan!? Why did she call Touma-kun
”
Kohaku’s face turns pale.
“Well, I didn’t expect her to secretly watch me enter Touma-kun’s room
”
“It’s okay. I should have called out to you on the spot if she was secretly watching. Anyway, I’ll attend the call, so please be quiet.”
(*Koku Koku) nodding Kohaku.
My heart was already filled with anxiety. I somehow managed to respond in my usual tone.
“Hello? What happened?”
“I’m sorry I called you so suddenly. Are you busy right now?”
“I was free. Is something?”
“Actually
 my sister is missing.”
Shirasawa-san said in a worried tone.
If it’s Kohaku, she’s beside me in a naked apron. Although I can’t say that.
“What do you mean by missing?”
“She is not at home
”
“Then is she not at school?”
“I thought so too. She told me earlier that she would be working overtime today, so I checked on her just in case. Then there was an unknown car parked in the apartment parking lot
 And even after I press her intercom, she wouldn’t attend
”
“Isn’t she out for a walk? Did you try calling her?”
Shirasawa-san should be convinced if Kohaku acts like she has gone for a walk.
“I can’t call her.”
“Why?”
“Because
 it’s scary. Onee-chan, she might be with a man
 If I interrupt her date, she might start to hate me.”
Shirasawa-san seems to be worried that she will end up annoying Kohaku. Surely she feels annoyed when her Oneechan, Kohaku, is bound by her father-principal.
But it might be a completely different story if it was some other party with her sister.
Because Kohaku loves her younger sister, Shirasawa-san.
Far from hating her, she should appreciate her concern.
“You’re worrying too much. She will never hate a good and lovely girl like you, Shirasawa-san. If I were your older sister, I’d want you to call me daily.”
“You are comforting me too much. Nijino-kun, you’re really kind.”
It was a soft voice with perhaps a smile on her face.
“You’re welcome. So what are you going to do about the phone call?”
“I’ll stop for today. I’m sure it’s just as Nijino-kun said; she might be just taking a walk.”
“But aren’t you worried?”
“That’s right
 but I don’t want to tie Onee-chan down. I do feel a little lonely, but it might be the time for me to leave Oneechan for her own life as well
”
She mutters the latter part sadly.
Then, getting cheerful again,
“Anyways~. I’m glad I called Nijino-kun. See you next week at school.”
“Oh. See you soon.”
After finishing the call, I tell Kohaku about the exchange with Shirasawa-san.
“Mashiro-chan thinks that I might have started hating her.”
“She seems to be feeling lonely. Why don’t you hang out with Shirasawa-san tomorrow and clear up all misunderstandings? If Kohaku, you invite her to hang out, I am sure Shirasawa-san will also feel at ease.”
“Yes. I’ll try and invite Mashiro-chan to hang out with me later.”
“I’ll be happy if you do.”
“Yeap,”
Kohaku nodded cheerfully and went back into cooking.
