Lily asserting her dominance over the MC's ex-GF...The only way she could have been more dominant and intimidating was if she was also T-Posing over the Ex-GF lol XD
Very nice communication...I doubt MC would have ever cheated on Lily due to not being the type...But now she is 1000% sure is going to cheat lol~
At least MC's ex-gf (Still kind of best-friendo from high school) at least accept the relationship that MC has (Just was a bit nosy and overbearing with her warning...Yeah Lily kind of has a bad reputation point due to her succubus nature/past.)
Best friendo also might be asexual or aromantic???? Or she just hasn't found the right person [Everyone is different and need more data, evidence and time to be 100% accurate though]....Though RIP to her boyfriend right now, he going to get dump soon lol~
