User blog comment:Artirtico/Head scratching over Love Interests/@comment-9290585-20130521195058

Love interests can be pretty messed up. Basically, it works like this: if you help someone with a quest, u get affinity.

Giving items to a person gives you affinity.

Punching them with no weapon lowers your affinity.

affinity carries over from each playthrough, meaning that if someone loved you in the first playthrough, they'll still love you in the second. Unless you punch them.
