About the "Orange" MV

Isn't that story about a jobless guy and a girl who got into the nightlife for him? 　And since she's busy with work, the guy gets really bored, and even when she makes him food, he says he doesn't need it because he's busy. 　So he thinks things were better before. But maybe when she actually disappeared, he realized that was happiness. 　However, I think the "disappearance" might also be a misunderstanding, which is where the matching keychains come in. 　The guy sees the crumpled half of the keychain in the trash and, in shock and anger, throws his own away. But later, a keychain appears on the girl's side too. 　This means the girl, maybe due to work or something, broke her keychain and replaced it with a new one. 　The guy, unaware of this and combined with her recent coldness, mistakenly thought he was discarded and ran away from home. 　The girl returned home to find the guy gone and was devastated. 　I think it's something like that. 　I really don't think she had given up on him at all. 　Ah, this is just one interpretation, of course.
