Avoidant attachment
Well if you look at it from Fumichi's stance, he never really had anything and no one ever really cared about him so he had no motivations in life but to keep doing what he was doing. He knew he didn't like what happens to him at the bar but he doesn't know anything better because he doesn't have that kind of support system.
I believe them infer that he had actual parents, but they passed away and he couldn't bond with his new guardians
I found this to be a rather melancholy story, not a cute one (though Iyo was cute).
Things just didn’t make much sense when it came to character motivations. Most especially with Fumichi. He is waiter at a bar where he got beaten up by a customer he offended. But he keeps working there, even when the customer returns, drugs and rapes him violently. And he still returns. Sure, there is an impression that the drug makes him forget a lot, but it makes no sense especially when you find out he doesn’t even get paid at the bar? Does he not need money to live?
The flashes of his childhood show him as a runaway with no attachment to his caregivers. But no reasoning why. Are they abusive, was he stolen, are they even his parents?
When saviour type Sazawa and his daughter, Iyo step in, Fumichi seems to fall for them both. But he resists that safety. Feelings of low self worth? I found him hard to relate to. I still enjoyed the story but overall it feels like too many missed opportunities to flesh out both of the MCs properly.
