In the feedback of a Monday TikTok, the Let’s Fall in Love for the Night singer responded to a person who took difficulty together with his sister Billie’s relationship with The Neighbourhood bandmate. A TikTok person made a video replying to one among Finneas’s earlier clips. In their video, the person stated, “Oh yeah? Well, your sister’s dating a 31-year-old man and your music is s****y” Finneas took to the video’s remark part with the phrases “I want my sister to be happy and safe and she is a 21 year old (sic) adult perfectly entitled to make her own life decisions.”
