Vincent and Rachel
Yana made several posts about the characters’ ages on twitter today, but to me the most interesting information was this one about Vincent and Rachel:
“Because his wife was young, *papa [*Vincent] would make himself look younger.”
The keyword here is 若作り (”wakazukuri”), I’ll just quote the definition from the dictionary:
“the act of attempting to make oneself appear younger than one is by wearing youthful clothing and makeup“.
So apparently, Vincent was (much) older than Rachel that he felt the need to make himself look younger to keep up with his young wife (appearance-wise) xD
