The pink one has a very big obsession and lack, he likes to corner you between the walls, his kiss is fast and intense, his hands like to stimulate your intimacy before the act. The only thing he wants from you is reciprocity and that you don't meddle in his plans and don't disappoint Manjiro Sano. If you let him down, you're also letting Sanzu down. It's good to always look back to see if he is not following you.
