Good job, mister "she's hardcoded to be my girlfriend as an absolute truth". This won't trigger an existential crisis and hard-crash her logic core, nope!
Kunihito may be mad because his friend isn't spending as much time with him anymore... But he ain't wrong. Creating an exceptionally realistic robot girlfriend without understanding (or even seeming to care) what that means is pretty messed up. Then there's the whole "I have girlfriend so I should have leveled up" like you just put a point in a skill tree to unlock a new perk. He needs some basic "how to human" help himself before even thinking about creating the next step in robotics and is probably why he keeps falling.

Now back to your regularly scheduled "This robot girlfriend was built too cute".
