Piano & strings BGM (6 tracks) for an indie idol ADV game "Afterglow"

Create 6 loopable in-game BGM tracks for Afterglow, a story-driven idol-raising adventure game for PC. Work will begin with one track, followed by the rest. Each piece should run approximately 1:30–2:00.
Tracks 1–5: One track for each of the five main characters, for emotional drama scenes.
The sound should be chamber-style, centered on piano and a small string ensemble: classically informed, romantic, subtly lonely, and faintly unsettling. Aim for restrained, cinematic beauty rather than overtly dramatic emotion. References include Lee Byung-woo, Yuriko Nakamura, Jonny Greenwood’s Phantom Thread, and Hideyuki Hashimoto.
Track 6: Reference: NCT 127 – “Interlude: Regular to Irregular” (from 1:55 to the end).
I’d like to reference the second half, where the calm, lyrical mood suddenly shifts and unsettling, alien electronic sounds emerge. This is not simple horror. I’m looking for a dreamlike, unstable soundscape where the line between reality and dream becomes blurred, and the sense of reality slowly fades away. I’m especially drawn to the distorted tones, irregular rhythms, and the unique sense of space that makes the listener feel uneasy. Please let me know if this style is within your range.
Deliver final masters in WAV and OGG, with loop points clearly noted. Virtual instruments are acceptable. One of the tracks should include a live recording of acoustic guitar or a string instrument such as violin; please indicate whether you can provide this and any associated cost. The game will have both all-ages and 18+ editions, though these requested tracks are not for adult scenes.
This is a full copyright buyout, including derivative and arrangement rights, for use in the game, promotional videos, soundtrack sales, and arranged versions. Credit may be under your real name, artist name, or omitted, according to your preference.
Budget:
Approx. $190–320 USD (¥30,000–50,000) per track, including the full copyright buyout
