Turns Out I Got My Own Happy Ending [Selfcest]

It's another past-and-future time-transmigration story, but this one's yuri, lol, and it's not long either^

Synopsis:

Some people are always reminiscing about their first brilliant days, while others are especially drawn to the glory forged through hardship.

When the one who reminisces and the one who yearns for what lies ahead reach for each other, they'll realize that I have always been myself, brilliant and glorious.

--

If love grows with time, shouldn't you love me most of all? After all, no one has spent more time with you than yourself, big sister?

--

I think I know who I love now. I always have, from the very beginning. There's no need to hide it.

--

Who are you?

The one who will add color to your world, big sister.

--

Me?

Yes, my rose.

PS:

The focus is on romance, with the plot in a supporting role. It has a few very traditional tropes, haha. The System missions, Gu Xingtian, and the like are mostly background details and only come up now and then, so don't worry too much about them.

Both are pure and take turns pursuing each other.

Theme: Accept yourself. You are wonderful.
