String on Tide

I haven't written it before, give it a try ꒰˶>ᗜ<˶꒱​ Pine wood piano room, ancient music and dusk. Two people guarding the border have a rising tide hidden in their hearts. Love piles up in silence, emotions are as tight as strings, and they will tremble and collapse with just a trace of external force. There is no out-of-bounds touch, only attachment that is on the verge of getting out of control, stopping at the critical point that will never overturn.
