It's not his secret to tell. Someone just told Naoto something in confidence and he was right that he shouldn't talk about it to Hazuki even if they're partners.
Plus, it's not that Naoto didn't know that Hazuki was being insecure, he even realized it right away at that moment. It's that he's not catering to and tolerating Hazuki's possessive and controlling bs anymore, especially when he brought up Naoto's past trauma in the argument just to prove his point (a misguided one tho lol). Sure it was said in the heat of the moment, but it was uncalled for and a low blow.
Good thing Hazuki caught himself and realized what he said. Hoping they'll communicate and apologize to each other in the next chapter.
Lining my thoughts exactly! You don’t have the right to keep secrets from your significant other especially not some random shit a stranger told you lol you don’t even know him the false loyalty is absurd af. Naoto is completely in the wrong
naoto should've just told hazuki abt it, hazuki has already been feeling insecure and then you'll keep a secret by someone who is good with kids?? then continues to gaslight hazuki when he is actually right that naoto is too trustful. lol. just say you don't care about what hazuki feels. i feel like naoto don't know much about hazuki by the way he acts.
