anyway i'm falling in love with you who does she end up with

In “Anyway, I’m Falling in Love With You,” Mizuho ultimately ends up with Kizuki in the main timeline shown so far.

Who she ends up with

• In the manga, it is revealed that Mizuho and Kizuki start dating around 2020, i.e., a few years before the future scenes shown in the anime.

• Kizuki later suffers a serious shoulder injury, quits swimming, and runs away from his previous life, which explains his absence and the emotional weight around him in the future storyline.

Anime ending vs manga info

• The first anime season ends with Mizuho reunited with Airu but still clearly affected by Kizuki’s absence and unresolved feelings toward him.

• The anime only hints at Kizuki’s future (returning from an overseas business trip and still cherishing Mizuho’s keychain), while the manga explicitly confirms that Mizuho and Kizuki did become a couple in the past.

Love triangle context

• Airu deeply cares for Mizuho and acts as her emotional ally, especially in rough moments, but he is positioned more as support than as her final romantic partner in the currently revealed canon.

• The story still leans heavily into the love triangle drama, and future seasons may add complications, but all official information so far frames Kizuki as the one she “ends up with” romantically.

TL;DR: Mizuho’s canon boyfriend (and the one she ends up with according to the manga backstory) is Kizuki, with Airu as her steadfast supporter rather than endgame love interest.
