Ou Keichou (王 慶張 Ō Keichō) is Kou Shuurei's childhood friend.
Overview[]
The son of a wealthy alcohol merchant, Keichou is Shuurei's childhood friend. Despite his best attempts, she repeatedly calls him by his childhood nickname "Santa," as she is unable to perceive him as anything but her childhood friend. He has a poorly disguised crush on Shuurei, though she does not reciprocate and is completely oblivious to his true feelings. His attempt to propose to her was dismissed because Shuurei has only ever seen him as a childhood friend.
