9/28 Subscrire's "Fader," a first-person portrayal of a woman with a strong female heart, will be transformed into a second-person song through collaboration, a collaborative release project that will be reborn in a variety of colors with each artist's lyrics and vocals. The fourth installment of the "Fader" collaboration series features Kyoto rapper BGY, leader of the three-member group "ROYALcomfort," which boasts more than 30 million views on YouTube. "I wonder if you can turn up the fader of my heart?" U.for sings about a woman with a strong feminine spirit that naturally shows glimpses of strength. "I know you're a sensitive girl who won't show your weakness. I'll bring you the best tone with my actions that won't lie to you." BGY sings about the feelings of a man who straightly accepts and envelops a woman with a strong woman's heart. This is a love song in which U.for and BGY men and women cross paths, depicted over a chill J-R&B sound with electric guitar & acoustic guitar phrases and the pleasant sound of an electric piano gently flowing.
