So I’m sure Furuichi fans will remember how Furuichi’s debut in the manga featured him plucking his eyebrows with tweezers, getting ready for a date. And well, we know how Furuichi is somewhat vain, so staying beautiful would be an obvious thing for him to do.
But cows-quack brought to my attention something I hadn’t noticed before. Furuichi is not only plucking his eyebrows, but he’s doing it in front of Oga. There is no doubt in my mind that if anyone else saw him doing this (or even knew that he did it) would tease him mercilessly about it, specially someone like Kanzaki or Paako. But Oga is eating cake instead, saying absolutely nothing about the subject, because he really doesn’t care or just doesn’t judge, and Furuichi is just that comfortable around him. They really are best friends.
…Makes you wonder what other things Furuichi might do in front of Oga, though.
