XO_willow is one of many projects of Trey Simmons, who is mainly known as “h3artcrush.”
This project was used to post many acoustic-focused songs, most of them having very controversial topics such as real-life tragedies, drug addiction, and misogyny.
Many of these songs are from when Trey was around the ages 13-15, and it should be noted that the song’s topics are explained by Trey himself as “completely fictional, and made up from my early teenage ramblings and thoughts.”

Trey has stated that there will be no more songs under this project, and as of early 2023, he uploads music under the projects “thai body dump” and “Crucify April.” He has not commented much on why he decided to discontinue any of his projects outside of the intro to his album—a whole lot of shit, where he states:

In closing, these projects are dead and will not be continued

It can be assumed that Trey has matured and lost interest in continuing to fuel the edgy, negative, and controversial topics present throughout this project, therefore deciding to start anew, experimenting musically under different titles—as well as distancing from his former self and actions.
