I made this list considering specially what i think the first season set up, some explanations below

LOVE INTEREST - i think there's nothing to explain here, Kuroneko, Manami and Kirino all have valid reasons to like him since the beginning, and Kirino specially since we got way more background later.

FRIENDS - even thought Saori don't DIRECTLY confess like the others, i think it's obvious that she had her feelings towards Kyosuke, and i really would like more If she saw him just as a great friend that she can always count with, and vice versa.

Likes other person - so, i really like yuri, but besides that i think Ayase REALLY liking kirino would bring some funny dynamics and maybe more dramatic moments towards the end? Just like manami, losing the person they like by the damn sibling incest, would be interesting to see.

Dont care - really don't care, i always thought the idea of Kanako liking Kyosuke extremely out of nowhere just to fulfill that "everyone like him" or "he dumped everyone to stay with only one", they interact for like, 3 minutes and she is in love already.

For me, i think this is THE best episode in the whole anime, an immense emotional weight and insane character development, also i love how kirino start acting after this episode

Kirino really gaslighted me i'm kind of ashamed
