On the morning of the day designated by Tre-san, I left home early and went to the Northern Area of the royal capital to reach the theater written on the map. Confirming things with a guide, I moved to the seat indicated on my ticket.

  Since I arrived early, there still weren’t that many people. That aside, I really wonder what Tre-san was thinking? If she just wanted to see a play, there was no need to use such a roundabout way…… Hmmm, I don’t know.

  Anyway, I read that I should check the second envelope when I get to my seat, so let’s immediately……


  [Errr, this should be the right seat…… arehh? Miyama-kun?]

  [Eh? Dr. Vier!?]

  Just as I was about to check the envelope, I heard a familiar voice, and turned around to see Dr. Vier there with a ticket of her own.

  As I looked at Dr. Vier, confused as to what was going on, I noticed how we both have envelopes that looked rather similar

  [……Dr. Vier, could it be……]

  [Miyama-kun, is that also from Sister Tre?]

  [Y- Yes, she sent me a lot of strange envelopes……]

  [Same here. Sister Tre asked me about my schedule, and I received these envelopes yesterday……]

  This was a little unexpected. I thought Tre-san would come, but I hadn’t expected that Dr. Vier, who would be in a similar situation as I am, would arrive instead.

  However, with this being the case, seriously, what in the world is Tre-san’s intentions?

  [……I wonder what’s going on?]

  [Hmmm, since it’s Sister Tre, I suppose she may have been influenced by some strange books or something like that? 80% of the time, Sister Tre acts without plans and without thinking about what the consequences will be……]

  [Yeah……]

  I was strangely convinced by Dr. Vier’s words. She certainly may have been influenced by some book that made her feel like giving instructions to me and Dr. Vier.

  In other words, Dr. Vier and I were probably caught up in Tre-san’s idea.

  [Ahaha, I’m sorry for Sister Tre, Miyama-kun.]

  [No, it’s not something that Dr. Vier should apologize for. This is just typical of Tre-san anyway.]

  [Indeed. Anyhow, I’ll be taking the seat beside you, okay?]

  [Yes. Even so, what exactly did Tre-san want?]

  [I don’t really know what Sister Tre is thinking here…… For the time being, I guess I’ll open the second envelope.]

  Dr. Vier’s words reminded me that I was also in the middle of opening the 2nd envelope, so I opened it…… and this time, it only had a message card in it.

  『Initiate your date with Vier!

  ※Open Envelope 3 after you finished reading this.』


  When I turned to Dr. Vier with the message card in my hand, my eyes met hers, holding a message card with the exact same content.

  As I was feeling a little confused, Dr. Vier’s face changed to a look of happiness.

  [……Ahh~~ I see, so that’s how it was. It can’t be helped. As a family member, I want to play with Sister Tre, and since we’ve already come this far, it can’t be helped, don’t you think!?]

  [I- I suppose.]

  Dr. Vier who became so much more excited than before is very cute, but my mind wasn’t able to catch up with how fast her change of thought changed, so I was a little overpowered.

  [……F- For the time being, I’ll open up Envelope 3.]

  [Unnn. However, wouldn’t the contents of our envelopes be the same?]

  [So far, the contents were the same but……]

  Thinking that the flow of the situation was rather strange, I opened the 3rd envelope……


  『Hold hands with Vier and watch the play!

  ※Open Envelope 4 after the play is over.』


  The flow of the situation really is turning strange. As I was thinking about this, I turned toward Dr. Vier, and saw that she, who had been peeking at the message card in my hand, had a big smile on her lips.

  [Unnn, unnn, I suppose this too couldn’t be helped. I guess we wouldn’t have any choice but to follow the instructions written on it. On the contrary, having such minor happenings while we’re watching a play was inevitable.]

  [No, it’s not inevitable…… A- Anyway, what about your envelope, Dr. Vier?]

  [Ahh, that’s right. Well, I think it will be the same……]

  Seeing how excited Dr. Vier right now, I remembered that time when we rode on Bell’s back together at the Six Kings Festival. Dr. Vier, despite her appearance, can be quite aggressive in her approach, so I was quite anxious when she was this excited.

  As I was trying to figure out what to do, Dr. Vier opened the envelope in front of me…… and she stiffened with a complicated expression on her face. Thinking how strange her reaction was, I looked at the card in Dr. Vier’s hand.

  『You aren’t allowed to do anything other than hold hands!

  ※Open Envelope 4 after the play is over.』


  There’s certainly the fact that the content of her envelope was different from my envelope, I think Tre-san anticipating and forbidding Dr. Vier’s actions was brilliant.

  [……Unnn, this is just, how should I say this…… Putting aside the contents…… I guess I was a little shocked that Sister Tre could clearly read my moves…… Am I actually that simple-minded?]

  [I- I dunno……]

  Setting aside whether she’s simple-minded or not…… the fact that her behavior is basically linear certainly makes her easy to predict.
