Hi Gege! Thank you so much for the lovely comment, I'm really glad you loved the game and that you could relate to it. <3 :D
As for the music, it's actually an original track called Pillow Talk! The track isn't currently available, but it will be soon on the artist's Spotify! So, I recommend you follow her (or just bookmark the page) so you can be notified when the track goes live. https://open.spotify.com/artist/7ptkQfjP52jOGGjXDHv2GG?si=259076acdca14f0d&nd=1
