It's a frightening thing to trust indeed, and she herself isn't the best at articulating words so this would likely be a difficult conversation with her, but she would agree that she hopes that they can find and befriend each other in the next life, and that wherever she finds herself Nene will find happiness - that all of them will. It's more subtle with her since she has a rough personality, but Nene is sensitive enough that I'm sure she'd be ale to realize that she genuinely cares about others and has just had her heart hardened by the school's culture.

She'll plant alstroemeria in her honor - flowers which represent are associated with friendship but also represent bonding through adversity. Their six petals represent empathy, understanding, humour, commitment, patience and respect.
