Wait who is this actor? Can someone remind me where he is from n their relationship?

i believe that is MC's first love from high school who broke his heart and caused all MC's relationship commitment trauma. MC thought they were dating until he saw the actor guy with a girl and MC tried to cling on to him but was pushed away

Ohh! Man he didn’t register in my brain. Esp woth everyone looking alike. Thanks! Yr a star!

no problem :)
