It is pretty sad that Shirokuma is so staved for attention and physical contact that she has to ask a relative stranger for some skinship out of desperation. Doesn't she have anyone else in her life ? We know she's not all that close to her sister but she has to have at least a few friends right?
@Speak_Evil I wouldn't be surprised if her husband doesn't really exist, and she's an insidious molester who pretends to be a milf to corrupt single girls.
