Since he started to live with Picchi, he firmly believes that she loves him just bc she was the only one capable of helping him out, so he ends up feeling a confusing emotion towards her (he tells her that he "loves" her with empty words, he lacks the real meaning of "love" bc of his mom trauma)

But he ends up just being really close to her, with no romantic intentions He's truly grateful for her help and she basically saved money to buy his first work setup (so he can live by himself)
