You'll have to try make sure you have nobody with pink aura all except Mercedes Marten till the fight of Grigori or Till the end of game if you like. Also, after "Pride before a Fall" quest, you'll have to make sure that you don't do the affinity-related quest with characters other than Mercedes Marten.

Ah. Escort-related quests obtained from Notice Board Quest also can increase affinity.

Just in case..
