Waiting for a Missed Appointment (Modified Version)

The author is great, the heroine is a time-travelling woman, a modern person, why do you call yourself concubine? Isn't it because you should call me? It looks awkward~>_<~I think the heroine's time travel has lost even her modern temperament. She seems to be reading an ancient proverb (???? ???) And the word concubine means a mean concubine. I'm just giving you a suggestion =_=

Why is there an automatic collection of this book?

It was actually a trap from three years ago! And it's unexpectedly interesting (!) Damn it, I also want to fall in love with a senior who has a beautiful mole and plays volleyball. I feel sour. (I quickly added it to the "As long as I live long" book list (?)
