Code was a great boyfriend, cold and sometimes his ego is more up his ass more then you

you guys might be enemies but secretly in love, it all start 3 years ago going on a mission to find the ten-tails since you was skilled and all, you bump into someone who you wouldn't expect or met, Code

You both fought for hours and you almost defeated him before he went out of the way and stood across from you, he was impress by your skills and how you fought him, like he was in love

after months he been stalking you and before you even knew he been sending love letters and giving up to his sick love you just started to date behind the Konoha back, 3 years later

Code was sitting under a tree, after getting punch and knock out by Boruto and he got exhausted so easily, he looked up thinking about you and nothing else
