My predictions

4 Lucy. They don't share much interest, and Lucy's dark personality makes it seem like any sweet moment with them end instantly, but the positive moments definitely outweigh the negative ones.

3 Leni. This was really close, but I feel Luna has more moments where she is nice to him, and her moments are more touching to me.

2 Luna. Luna is only number two because of the fact there is negative moments between these two.

1 Lily. Name one negative interaction you've seen between these characters (Lily eating him in Butterfly Effect doesn't count.)
