Boy Meets World (1993-2000) was mostly about the romance between high schoolers Cory (Ben Savage) and Shawn (Rider Strong) -- even Cory's girlfriend Topanga (Danielle Fishel) commented on it.
But when Cory married, they needed a new buddy-bond, so during the 1999-2000 season, Matthew arrived as Jack Hunter, Shawn's older half-brother, who immediately fell in love with Cory's older brother Eric (Will Friedle).
2. In Jumping Ship (2001), Matthew plays Jake Hunter, a sullen sailor hired by Michael Woods (Joey Lawrence) to sail him and his brother (Andy Lawrence) to Australia. On the way they are shipwrecked, learn to work together and care for each other (with their shirts off, naturally), and by the time they are rescued, they have become permanent partners. The movie ends as Michael is introducing his new partner to his dad.
3. In Cheats (2002), about high schoolers who run a test-cheating business, Victor (Matthew) is obviously in love with Handsome (Trevor Fehrman). Yes, he's actually named Handsome.
He also rips his shirt off.
In case you were wondering, yes, he does take his shirt off in almost every movie.
