The Melancholy of Haruhi Suzumiya, Volume 17 — Nagaru Tanigawa

One weekend, when Kyon reaches the usual SOS Brigade rendezvous spot, he is met not by his fellow club members, but instead by Sasaki, an old friend from middle school. Haruhi isn't thrilled to find Kyon already waiting when she arrives (Who's going to buy drinks?!) and is even less thrilled by his attractive female friend!
