A and B meeting for the first time and A really really thinks B is cool and amazing and would really want to learn from them! As such, they decide to call them their mentor! B tries to tell A that they don't want to be their mentor but A doesn't care.
Later it's revealed that B is actually a bad guy or something! A feels really betrayed about it :( B tries to clarify that they never agreed to be on their side anywaysWow sorry if that was confusing or hard to read
