The song is about the relationship between BTS members and how their relationships are very similar to a house of cards. They are very light and they can easily break with a simple mistake. It can collapse in just a short time even if they try their best to save it.
They are scared of how long they will keep holding onto each other and what will happen if someone will leave them. They are afraid that the house of cards will fall one day and they will lose all their hard work and everything they have built up so far.
It is a sad song that is not about any desirable fantasies but it is about the trust that they have for each other. They are not sure if the love will last but they want it to and the hope is very high that their relationship will continue to stay strong.
The lyrics are about the bond between HYYH Jungkook and HYYH Yoongi. They are the only ones that can understand each other and the bond that they have is very special.
Their relationship is very light and they can easily break with slighlty mistakes but they try their best to save it. They are afraid that the house of cards would collapse in just a short time even tho they try their best to save it.
They are trying to ignore the fact that their relationship is toxic and they are hurting. But they cannot because it will just make their regrets stronger and the house of cards will crumble again.
