(I'm bad at writing blurbs. The male lead will come around, so you can check the comments before reading.)
After transmigrating, Nishimiya Yu discovered that he had arrived in a world teeming with anime heroines.
He wanted nothing more than to go home, but the System told him that he could only leave if he achieved the supreme title of [Harem King].
To accomplish this little goal, Nishimiya Yu kept fit and studied hard, while the System helped him max out his arsenal of flirting skills.
He even planned chance encounters, engineered misunderstandings, scripted scenarios, and plotted confessions, all in an attempt to create happy memories for every heroine.
But after all that effort, all he got were one bad ending after another, each ending with a knife.
[Player has died. Reset the worldline?]
[Yes.]
After a long passage of time and tens of thousands of reloads, the persistent Nishimiya Yu finally found a way to win over every heroine perfectly.
This time, though, he wore a cold smile.
"I remember every bit of pain you caused me in those 9,999 Bad Ends."
"So this time, I'm getting revenge. I'll make everyone fall hopelessly in love with me and confess to me of their own accord."
"Then I'll reject them, one by one!"
Is the author still writing books? This book is really well written.
