I think the only reason Chiaki would ever get hurt from Enaga saying he's Ai is by the way he says it. If Enaga is like "Both sides are truly me and I care for you as both Ai and Enaga, if anything I've fallen for you. I've been scared to tell you because I have been worried about betraying your trust but I can't hide it from you anymore" sorta thing then ofc Chiaki would feel relieved. But if Enaga/Ai is just like "sorry..." then it'd be the end. LMAO LIKE PLS
