SP1

SP1 is one of Chan's bodyguards. Though a bodyguard for one of the world's richest people, he never received any formal bodyguard training.

Peevee developed a crush on him after he visited her bar. SP1 reciprocated these feelings, and visited her bar nightly afterwards.

It is likely that SP1 is the actual Chan, and that the person posing as Chan has another name. This might be to protect the real Chan's identity. However, the explanation behind why Chan and SP2 call SP1 "Chan" is unclear.
