A song that also reminds me of them (specifically the breakup arc) is “It Took Me By Surprise” by Maria Mena.
“I would react badly to the slightest hint of hesitance
He’d bend awkwardly to suit my mood,
No word from his defense
I’d cry knowing how my tears felt like acid burning through his skin
Pushed every little button but the right one that would let me in
Now he’s afraid of me
He’s afraid of me”
“It took me by surprise,
The hatred in his eyes
I’ve pushed this man as far as he could go
But he lacked the word to let me know
He acted out, now I concede it is my fault”
OH MY GOD THAT'S PERFECT FOR THEM
ESPECIALLY FOR THE SCENE WHERE SEKYE GOES TO YIJUN'S APARTMENT AFTER SEEING HIM WITH THE ACTOR
Arckk!（/TДT)/ I'm currently at chap 38 and in the chapters before this all I have in my mind about Sekye and Yijuns relationship is that it reminds me so much of Olivia Rodrigo's song "The Cure." Like the lyrics
"All because my head is full of poison
And my heart is full of doubt
I've got toxins in my bloodstream
You tried so hard to suck out,
And it feels like medication
And it's good for me, I'm sure
But it don't matter how your love feels anymore,
It'll never be the cure..."
Laykkk arghh I'm literally torn to pieces right now ┗( T﹏T )┛
