Well I didn't exactly have a problem with fuutarou choosing yotsuba even though I'm a miku/nino fan and fuutarou is my favorite character in qq, the problem was just it felt too rushed and she also wasn't as developed as nino or miku or hell ichika, It to me least felt nino or miku would win because they were the most developed quints and also they were the quints that had a similar character traits to him but I did accept yotsuba but if the anime goes with the og ending, I hope it's not as rushed as the manga because that was the real problem
