In the meantime is sung by TRIGGER's voice actors, Wataru Hatano as Gaku Yaotome, Soma Saito as Tenn Kujo, and Takuya Sato as Ryunosuke Tsunashi. The lyrics were written by Aira Yuki (結城 アイラ, Yuki Aira). Shun Kusakawa composed the song while GRP composed and arranged it.
In the meantime was released as part of the REGALITY Album on September 20, 2017. It was also released within the game. If you clear Part 3 Chapter 14.4 it will be available within the normal lives.
You know where you want to be, but you have no clue how to get there. You know exactly what you want in life, but what you want is nowhere in sight. Perhaps your vision is unclear, your purpose still undefined. On top of it all, your relationships, particularly your romantic relationships, are failing. If these scenarios feel familiar way down in the deepest part of your gut---then you, my dear, are smack dab in the middle of the meantime. Your mother, bless her heart, and your father, with all of his good intentions, did not prepare you for the meantime. They did not because they could not. No one can prepare you or help you find what you are looking for. What you need is love, not romance. Love, not more money. Love, not a new car. Love is the only thing that can make the meantime worthwhile. Once you find love, true selflove, and unconditional love for everyone all the time, things will look, feel, and be a lot better. The question is: What do you do in the meantime? Every living being wants to experience the light of love. The problem is that our windows are dirty! The windows of our hearts and minds are streaked with past pains and hurts, past memories and disappointments. The windows are so clouded by fear, self-doubt, and inaccurate information that the light of love cannot shine through. In the meantime, we keep looking through the foggy window, trying to convince ourselves that what we see is the real thing. It's not, and we know it, but we can't seem to figure out what to do until the real thing comes along. What we must do is clean. We must clean the windows, floors, walls, closets, and corners of our mind. We must mop and sweep away the stuff that trips us up, keeps us confused, and makes the meantime miserable. In this book, Iyanla Vanzant tells us how we can do this thorough mental housekeeping. If we do a good job of it, the light will come through. Once that happens, our spirits will shine, bringing in the light of true love and happiness.
