Does hitting "B" during an evolution lower happiness?

Okay. So, I’m leveling up my treecko and I was using lucky egg to gain exp faster, but I have to stop evolution every time it levels up. So I was wondering, “Am I lowering it’s happiness by doing this?”. Hope you can help!

No, stopping a Pokemon from evolving does not affect happiness in any way.

Its happiness will stay the same even if you stop it from evolving.

Doing these things do not effect happiness.Source- Depositing a Pokémon in the Pokémon Storage System- Healing a Pokémon with low HP or with a status condition- Giving a Pokémon an item to hold (except the Soothe Bell)- Evolving a Pokémon, regardless of method (level up, held item, or evolutionary stone, with the exception of trade evolutions, which reset the Pokémon’s friendship)- Using a Pokémon in battles- Winning battles with a Pokémon- Letting a Pokémon’s HP fall to critical status- Letting the player’s Pokémon get a status condition like paralysis- Walking when the player’s Pokémon has a status condition- Affection in Pokémon-Amie

I hope this helped.
