It's Fine to Fall for You, Right? (Fujiwara no Mokou X Male-reader)

Thirteen hundred years ago, a girl drank a Hourai Elixir. A thousand years ago she went into hiding, away from the spiteful eyes of the public. Seven hundred years ago she unleashed all of her emotions and destroyed everything in her path. Four hundred years ago she was filled with everlasting boredom.

But within that age of dullness, she met a man and somehow fell for him. It was an accident of the heart despite knowing that she will outlive him just like how she will outlive everything else in the entire world.

And she was right when she heard her beloved supposedly died in a terrible incident. She lived the rest of that boresome life in heartbreak and loneliness once again. That was until Kaguya showed up once again and she was filled with ecstasy.

But what if after one hundred more years of fighting with Kaguya nonstop, she sees the man she thought died all those years ago? Within the House of Eternity even more.

How would she react to see her long lost lover after all these years? Can her long-broken heart be mended? Will she go off to kill Kaguya again for not mentioning at all? Will Cirno fulfill her quest at becoming the strongest in Gensokyo?!

All will be answered. After all,

"It's fine to fall for you, right?"
