This is a meh one shot but the girl's revelation to the MC of why she have never had a bf is somewhat interesting to me. She just wants to get the order right, which is to get to know each other more before taking any steps further. Many people confessing to her did it on their whim, out of the feeling of pride of dating a beautiful girl. She senses the ephemerality of these potential relationships, so she turned all of them down and become an "unobtainable flower". At the same time, this sparkles some opportunities for our lucky MC, who is actually deeply in love with her.
I would actually want the author to take this premise even further. But oh well, it has been nearly a decade and I could live with this. Thanks for the translation.
