Compare members to UMESHU (*Sake with plums)

Tegoshi would be the PLUMS.
I think that the plums should be Tegoshi. There can't be an Umeshu without plums. There would be no flavor without them. The plums before being used for Umeshu are sweet and fruity like peaches, but plums are usually seen as sour, isn't it unexpected? Their sweet scent is close to Tegoshi. His image is very sweet and cute, he has a strong feminine side. But if you try to bite the raw fruit it'd be very hard, so bitter and difficult to handle! (lol) That's why he's like a plum.

This was like the weirdest comparison anyone had to do but at the same time amazingly accurate.
