“It’s not that much since it’s for Shiho. Keep it a secret from Shiho though. I didn’t tell her that Tojoin might come and disrupt the date. She was looking forward to this, so I don’t want to unnecessarily worry her.”

“You’re such a good girl…! I love you so much…!”

“You’re not even hiding your feelings for Shimada anymore now, are you…?”

Yuuichi is saying something, but I can’t hear him.

Hah, Sei-chan is so nice that it hurts.

Sei-chan plans to bear the burden of making Fujise and Yuuichi date a success, without telling Fujise about it until the end of the date.

‘I don’t want to be thanked by Fujise, not even for a second.’

‘I just hope that my best friend’s love will be fulfilled.’

I was able to fall in love with this girl. Then I was brought into this world, and was even able to confess my love to her first hand.

That alone makes me insanely happy.

Compared to Sei-chan’s feelings for Fujise, I’m really no good huh. I’m really blessed to be in such a situation.

When Yuuichi suggested it, I said, “It’s too much work for me and Sei-chan.”

But Sei-chan suggested it herself and even tried to hide it from Fujise so that she wouldn’t be worried.

It’s so awesome and cool, I love it.

Huh, I’ll stick some skin in the game for you.

“Eh, then…!”

“I’m coming with you, to protect you and Fujise’s date.”

“Oh! There’s my Tsukasa, My~ best~ friend~!

“You’re acting like some kid singing a lousy song in some vacant lot.”

“Haha, I’m a pretty good singer if I do say so myself!”

“I know.”

I’ve listened to the drama CDs of “Ojojama” from the previous world, and you had a crazy cool voice actor, you know?

I haven’t been to karaoke with this guy ever since I came here, so I’d like to hear him sing a cool song with such a voice.

“If we make it through this, karaoke’s on you.”

“Of course, I’ll do that at least.”

“I’ll take the most expensive set I can order.”

“Please don’t do that.”

We both looked at each other and began to laugh.

Alright, I’ll send another message to Sei-chan.

“I can’t let Sei-chan go alone, so I’ll come with you to protect Yuuichi and Fujise’s date. Let’s do our best together.”

Sending…

“Me and Fujise have really good friends.”

“It’s true. You can thank me and Sei-cha… Shimada for that.”

“Of course. Also, you can call her Sei-chan in front of me if you want, I already know about it after all.”

“Shimada says I’m only allowed to call her that when we’re alone, so absolutely not.”

“…Well aren’t you just boasting about it now?”

“I-I’m not boasting!”

“No, that was definitely boasting… So you guys are going on a date tomorrow as well I assume?

“Eh…? Ah, I-Is that so?”

“Tsukasa… Did you not realize”

We-Well, I see. If we’re both going to go and protect Fujise and Yuuichi’s date, that means me and Sei-chan are going to be alone with them, too…!

Oh, man, that message I just sent her, if you think about it carefully, it looks like I’m asking her out!

I wasn’t aware of it at all, but now I’m starting to get nervous.

What if she refuses to go with me…?

I looked at the message screen and saw that the message I had sent earlier had already been read.

We-Well, I haven’t heard back from her yet but… I’m afraid of what she’ll say now.

“O-Oh, you’re making me feel so nervous all of a sudden…”

“No, it wasn’t a big confession… I mean you’ve already proposed to her, right? Then this should be fine.”

“It was not a proposal.”

I did confess to her, but most of the confession that I had made that day was a bit bold because I thought that I was dreaming.

The message history that Yuuichi just saw is also the messages that I had sent whilst in that dream tension…

Although I didn’t mean to say that to her in reality, I meant everything that I had said to her that day.

Idefinitely want to make Sei-chan, who’s basically been confirmed as the losing heroine in the story, happy.

I’m not going to let it end sadly.

I think it’s going to be okay ……, but I’d be so depressed if I got rejected.

–Pom-Pom, a peculiar sound came from my phone.

She replied!

The message screen shows…

You’re coming too? I’m reassured having you on board. Thank you…

“Lets go!!”

Whoa! Don’t just shout out of nowhere, you…!”

When I saw that it was accepted, I yelped out loudly.

Thank God, I didn’t get turned down by her…

I mean, really, I’m going on a date with that Sei-chan tomorrow…!

No, the two of us would be working together, sure. The goal was to keep an eye on Yuuichi and Fujise’s date and prevent Tojoin from interfering with them.

Don’t mistake means for purpose.

“Me and Shimada, we’re going on a date!”

“No, that’s true, but you’re going to protect our date, right?”

“Of course! Okay, what should I wear tomorrow…!

“Do you really understand or no…?”

Yuuichi was worried about tomorrow, probably because I was so excited knowing that I was gonna go on a date with Sei-chan tomorrow.

Well, I’m looking forward to it nonetheless.
