Absolutely agonising depiction of the pain of separation (airport departure boards, ticking clocks, solo Tube rides home, time differences, missed calls) and the toll it takes on relationships when you're young. The compromises you make. The tiny deceptions. The hyper-reality of love compressed into the small amounts of time you have together. The way your lives change in all the imperceptible ways while you're apart.
Totally broke my heart.
