Yeah between him being kind to her, Bella liking him (which in turn makes her like him more), and him knowing nothing about her family is just pure gold to her. Loving and appreciating her for just being Jill; I can get behind that. Then to top things off we're playing songs for her on our guitar too. Which wouldn't surprise me if we have to use what we are practicing to save her at the performance she's going to have because she gets too nervous on stage by herself.

Then we have Tybalt just making MC look even better when he makes asshole moves against him. Her text about "Thinking a lot about you too" and the cute "correction" after says it all.
Also by the time we see Bella again I'm pretty sure she going to have heard the full story endlessly without the MC needing to say a word. lol
