i'm pretty sure it wasn't. it's very common for a teenage girl like her to have a crush on someone older. they think it's love but really, it's just admiration.
considering that Tanaka Kei did in his real life and cheated on his fam with another woman, I guess we either…
ya but I've seen it too many times in japan that they like to shame the woman involved more so I wouldn't be surprised if he comes back in a new season after just a slap on the wrist
