Brian & Justin. One of my absolute favorites: playful, joyful, nonetheless earnest and touching. Justin as the infatuated teen he actually is and Brian as the affectionate and caring grown up he seldom allows to show.
“I want you safe … And I want you around for a long time” expresses IMHO more romantic than any “I love you”s or a bed full of roses :D.
Maybe the scene where the uncertain future of this couple / love becomes plainest apparent.
