The harem would not be too large(I'm not sure how many but probably just 4-5 main and few other here and there). All the girls would be getting their time and story.2. The story is starting when the MC is in the middle of his growth stage and not at the very beginning. But his beginning will be mentioned in the story in some form.3. I don't think I need to mention this, but obviously it will not have any NTR, rape or that kind of stuff.

Cheng Yin likes her deskmate Chen Yan for a long time, but she never dared to confess her love for him, and the phrase ‘I like you’ is a secret hidden in her heart, but she can’t help but blurt it out from time to time…
Cheng Yin: “Chen Yan, I’ll whisper something to you.”
Chen Yan always leans over quite cooperatively, “What?”
The words came to her lips, Cheng Yin blushed and changed it into: “Your pants are unzipped.”
Chen Yan: “?”
Later, this kind of useless whispering has become more frequent, and Chen Yan listened again without moving a bit: ” Speak.”
The day of the party, Cheng Yin drink for the first time, Chen Yan became two in front of her eyes, she grabbed the person with both hands, want to try to catch the real Chen Yan, only to have her hand caught, he lowered his head in her ear and said: ” Let me whisper to you.”
Cheng Yin: “…… what?”
Such bad behavior, she thought it was something bad, Cheng Yin checked her pants and made sure the zipper was closed before she lean over.
The man’s breath blew softly in her ear, laced with a bit of the smell of wine.
“I like you.”
