These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: To Heart
Asspull: Kotone canonically harbored feelings for Masashi in the first season, but when Remember my Memories rolled around, she confesses to Hiroyuki out of nowhere.
Masashi also did confess to Akari in Remember my Memories despite the above, and Akari knew of his feelings towards her all along, calmly rejecting him.
Sequelitis: Arguably Remember my Memories, due to many reasons: the Asspull that was Kotone's confession to Hiroyuki (as well as Masashi's to Akari), Multi's Hostile Show Takeover and Hiroyuki upping his Jerkassness towards Akari before finally falling for her did not rub many fans the right way.
Also splitting people is the different art style, taken straight from the game.
The Woobie: Kotone Himekawa. Her parents are never around, she's got Psychic Powers that cause people to avoid her, since getting close to her supposedly gives you bad luck because she can foresee any unfortunate events that would occur to anyone close to her.
Subverted in Remember my Memories when she becomes best friends with (and manager of) Aoi Matsubara, though for a while she nearly goes back to being The Woobie when Aoi's popularity skyrockets after the latter's championship fight.
