OHMYGOSH OKAY watanagi anon here!!! i just really like to see them as some kind of anchor to each other. like wataru keeps nagisa from getting lost in the earth and nagisa keeps wataru from getting lost in the sky. they both have very different personalities and i think they complement each other so well? wataru tends to lose himself in the "sky" meaning his own role, his own performance, his own play, something higher than him, up in the sky.. that keeps him away from reality somehow. and whenever its necessary, or whenever it starts to get dangerous, nagisa has the power to get wataru's feet back on the earth. and in the other hand, nagisa tends to get lost in the thoughts, in the words.... i cant really explain it but it feels as if his feet are So on the earth that he never allows himself to fly in the sky for a while. and its wataru who takes him and shows him theres a whole world he doesnt know. while nagisa shows wataru about the world (not the play) he lives in. sorry gosh this is like so vague and abstract i hope i make sense 😭😭😭😭 wataru also likes playinf with nagi's hair and braiding it If you even care. he loves nagi with his hair down and really likes to brush it...... Whatever
