And the romance genre was doing so well.

Futaro Uesugi is an academically gifted student but stuck in a bad financial situation with his family, an opportunity presents itself as he is hired to tutor the Nakano quintuplets, Ichika, Nino, Miku, Yotsuba and Itsuki with each one having a different feeling for Futaro.
Ichika is Tsundere towards him.
Nino is Friendly but wouldn't go all the way.
Miku is clearly in Love.
Yotsuba is Playful and never disliked him.
Itsuki just hates Futaro.
Wait a minute, this is just Love Hina!
And if you disagree, plot twist, he met one of them as a child and made a love promise, that's literally Love Hina.
And it makes it all the more disappointing, but what I find more egregious is how little the Quintuplets care about their situation, if it weren't for the plot point of Futaro needing money, he seems like the type of guy to just say "screw it you're on your own" as the fact that they are so rich, they couldn't give two shits about their education, they don't even complete their main goal in season 1, they just ass pull saying that combined we technically pass.
As for the girls, anything less than Miku winning, the only girl who actually has chemistry with Futaro, I do not recognise.
The dub is pretty standard fair.
Final Verdict: A poor version of a romance anime that was already doomed to fail the moment you realise you're watching a poor man's Love Hina, Miku is literally the only character who deserves to win.
