I Would Suffer For Your Landscape (слэш)

Alec keeps finding himself at the base of Magnus' fire escape after evening patrol duty.
"It went like that until Alec ran out of arrows, Magnus trying different tricks to trip up his shadowhunter house guest and Alec hitting the target each time. By the end of it, they were both a giggling mess of competition and blooming attraction. Alec couldn’t tell if he felt giddy from pride at hitting each target or simply hitting each target for Magnus. He felt young and light and a little like he could fall into this, whatever this may be."
