I Went Back to Being a High School Student Again, but I Was Rejected by My Childhood Friend, Whom I Thought Was In Love With Me, So I tried to Suicide With the Most Beautiful Girl In the School. - Chapter 16

Speculation

　It was the next day after I went to Natsuki’s room.

　I took a day off from my part-time job to think about what I should do to keep Natsuki Mirai alive.

　If I did not do anything, she would end up in the same situation as last time.

　What I should do to prevent that from happening is to avoid the incident that happened on the first day of the festival.

　After that day, the relationship between me and Natsuki has changed.

　I should never have left Natsuki alone on the rooftop, shivering back then.

　So this time, I’d like to eliminate the reason why Natsuki was left alone in the first place.

　The reason why Natsuki was alone on the rooftop that day must be because someone in the school harassed her.

　Then, she lost contact with me, and without anyone to rely on or to be saved by, she chose to die by herself.

　That’s what I was hoping for on my second life.

　――For her die with me.

　But this time, I want her to live so I can die with no regrets.

　I’m so self-centered and low-life as a human that it makes me want to vomit.

　I know self-mockery will not change my current situation…

　That’s why, at least, I have to use my head and think about who might harass Natsuki.

　――If it is only a possibility, it is all the students in the same school.

　Natsuki is disliked to that extent.

　However, Natsuki should not be so harassed by the usual level of harassment that she is driven to the point that she does not have the energy to put up a bluff.

 　Then, I can think of two people who are likely to harass Natsuki more severely than usual――

　The first is Iori.

　She seems to have stopped harassing Natsuki after I told her to stop, but she was the one who disliked Natsuki the most in the first place.

　It is quite possible that she will harass Natsuki more severely than she has been putting up with so far if she gets a chance.

　And the other one is Koyoi.

　Koyoi had ignored Natsuki before and even disliked her enough to speak ill of her behind her back.

　But I remember the look of jealousy in Koyoi’s eyes that I saw for the first time after the summer vacation.

　At that time, I had admitted that I had become friends with Iori without any hesitation, but I had shown my anger when she questioned my friendship with Natsuki.

　If Koyoi is the culprit, the trigger must have been that very moment.

　――Though this was only my speculation.

　I don’t know who the culprit is because I hadn’t talked with Natsuki from the first day of the festival to the last day when we jumped down together.

　If I had been there for her then, at least I would have had no trouble finding the culprit.

　――I shouldn’t let that mistake be in vain.

　I…I can always avoid tragedy if I can use the experience of the last time properly.

　I operate my cell phone and open the phone book.

　I select her name from the list and make a call.

　After three rings, there is a voice answering the phone.

[Hello?]

　Hearing those words, I told her directly.

“Next time, I have a day off from my part-time job. Will you go on a date with me? “
