I think that this song can be relatable to Jaehee's younger life after her parents died. You know, when her aunt and uncle took her in but didn't see her as anything but a burden. When her aunt kept disrespecting her dead mother by judging her life choices. When Jaehee had to work extra hard in life just to try to get her aunt and uncle to not see her as a burden? Yeah, this song relates to that life a bit... just a bit. Not too long in the song it just starts to relate to her so much.

You criticized my choices

Not only had her aunt judged Jaehee's mother for her choice of marrying an older man, she probably started judging every 'wrong' move Jaehee made. Probably judged her tenfold just because she was Jaehee and she was the extra mouth to feed.

I let go of bitterness that wouldn't leave or let me grow

She did, in fact, let go of all bitterness to anything. The death of her parents, she accepted. The emotional bruising, she accepted. She didn't exactly hold any hate or bitterness to anyone no matter how much they hurt her. She let everything go and just tried to live. She grew as a person because of that.

I could spend a lifetime trying to understand why someone sharing my bloodline would not lend me their hand

Her aunt did help her from being an orphan, yes, but the emotional wounds that was left on Jaehee was not good. Her aunt didn't really see her as anything, just a waste of space. She saw her as something that didn't even matter, not even taking into account that she was her niece. She was an option. Her aunt didn't even really want her to be there, by what I saw.

Am I supposed to apologize?

I believe that younger Jaehee would always apologize for everything she ever did. She probably tried her best to not take up too much space and tried not to be as much a burden as her aunt described her as. She probably apologized over and over again for being alive.

Followed the crooked path that led me to a stage. The curtains opened up, my heart followed the lead. The music wouldn't stop and I could finally breath.

When Jaehee probably first started watching musicals, it finally gave her a happiness that she probably didn't even know she was being deprived of. She could probably be able to breath and be herself without apologizing for every breath she took. She found a love for music and acting but never pursued it. Maybe because she didn't try/ didn't have talent or... didn't think she was good enough and thought she just deserved to watch. This is probably why she developed a crush on Zen. The happiness that she connected to that first musical she watched probably connected to Zen unconsciously because of his occupation. Plus Zen is a really nice dude so. Musicals are probably Jaehee's favorite things because it was probably the first thread of happiness after her parents died.

Of course this is all just my take on the lyrics and why I think they could apply to Jaehee. Some of these things I said might not even be true about how she thinks or what she feels so I say probably or maybe and stuff like that. I haven't played her route in a while but I distinctly remember her aunt calling her a burden and not speaking to highly of Jaehee's deceased mother. Those were Jaehee's memories most likely so that meant Jaehee had been within earshot to hear everything her aunt really thought of her. This is how we got workaholic, not taking breaks, too efficient, coffee blooded Jaehee. Anyways this is just how I think the song could fit her so don't attack me, please. I might be wrong because shit memory but still.

Anyways did I help you find a new song you like?
