Identifying & replacing/ adding/ Buff to outcome of prompt

I'm trying to create a different, less-intense reaction to an in-game scenario, where in the game if you choose "No", the Sims develop lengthy negative buffs and sentiments. I want to replace the buff if I need to, because i'm not fully sure what it is, and remove the sentiments:

I've lowered the relationship impact, but I am confused on:

1. How to figure out what "buff_reason enabled 0x1D77B780 From Friend Rejection n=buff_type 297948" means. I've looked around and can't figure what what buff it relates to. I created an embarrassed buff in ModConstructor but I don't know how or if it would connect in order to place whatever the existing buff is.  I want the Sim to feel moderately sad and/or embarrassed for a couple of days. 

2. To remove the negative sentiments from ever happening in this interaction, do I just delete the 3 instances in the bottom: buff_NPCRelationshipAutonomy_GenericCommitment, loot_Sentiment_AddSentiment_Bitter_NeedsDistance_TargetToActor_Friend, and loot_Sentiment_AddSentiment_Hurt_Rejection ?

Thank you!
