I thought he will have the elf girl in the future, so why does he have to show affection to the girl?
Oh maybe for harem what peice of shit author
Moral dilema.
You have a lover, she dies, and later you love other one.
You go back in time, so your first lover is alive and you can save her life.
And you loved them, but you also loved another one.
Who is the one you trully love?
Your first love that you lost and got back, but you arent the same one who loved them.
Or your second lover that is still around and doesnt love you back as the chain of events that made you love each other no longer will happen.
