So I've been following stories like this for a while now, and I don't know if the authors were ever Hikki themselves, but that's not usually a lifestyle endured by choice. It's one the person either falls into by accident or one who seems forced into it by unfortunate circumstances. They try and try and always end up failing and so they give up, it's rarely ever "Well I'm just lazy so that's that and I'm perfectly happy like this!"
That's pretty far from how most Hikki would feel. They want to interact. They want to have relationships. They want to be themselves. It's just that they feel they can't. So it's quite curious to my why the Hikki characters are always so excessively happy to be Hikki themselves because it feels like the japanese mindset is that these people are just choosing this lifestyle out of laziness.
