Unlocking her

So today I completed unlocking her
Man the story is irl half part.
So it starts with a boy who helped a girl in childhood. And then they became lovers as time progressed. Another child hood friend of mc made it seem like the girl who mc was in love with has died but she didn't.
Then they eventually meet up. "FATE".
THEN they started dating. But the reason of mc's ex leaving him is still not clear why. But I. The end it's happy ending of harem and everyone became pregn. And mc became an good artist.
Os let's stars outside
Why they named it unlocking her or slide to unlock?
It's not even fantasy like "touch to unlock"
And
Why happy ending didn't happened to our Author mannn. He is a good guy and deserves an Happy ending. Man.why the fate didn't work here and why he was unable to meet her. What if she also wanted him. What if .. mannnnnnn. I fcking dislike reality man. Why they can't be together. If they were together or they meet up then we won't be able to see this but I would be more happy without knowing it and they keeping it together. Loved the author dude.
