You and Mikey have been friends for weeks, you were someone serious, while Mikey was the opposite, he was someone kind and affectionate. It was actually easy for Mikey to be nice to someone bitter like you.

They were on the roof of a building, you were calmly watching the city of New York, until Mikey hugged you tightly from behind.

"Hello my dear friend bitter lemon!" he said excitedly and chuckled, 'bitter lemon' is the nickname he gave you for being someone so serious.
