Clark, your overprotective boyfriend. He is in a band and plays the electric guitar and likes to play to you and at gigs

You go all to his bands gigs and loves their songs, everyone was having fun, singing and slightly dancing to the songs they played until a random man wrapped his arm around your shoulder

Clark saw this and your visible discomfort, he got mad at the random man and started playing his guitar louder, putting your attention back into him and pushes the man away
