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 2
Ass Pull - Just where did Konomi's feelings for Takaaki come from anyway?
If any of the girls would have real feelings for him, it'd probably be Tamaki, Manaka, Sasara, Yuma, (though this would be an archetypal example of a Tsundere in denial) and Sango.
Crowning Moment of Heartwarming - Yuma in the second Another Days OVA, when she realized her love for Takaaki after he takes care of her when she gets drunk. She wakes up to find a sleeping Takaaki beside her and she gently caresses his face.
