What’s with this trope of the light haired boy being in love with the dark haired protagonist

Bonus points if the dark haired boy is oblivious, it’s unrequited or they get a tragic ending

Me: *reading gay porn fanfic in public space*

Person across: *stares*

Person: *keeps staring*

Me: *feeling guilty, close the fanfic and go see cute animals pics*

Mixed emotions
  • Tv show: *some random dude/gal dies an emotional death*
  • Me: oh poop, that just got real. Dang
  • Me: *sees a picture of otp*
  • Me: *starts crying*
  • Friend: what? What's wrong?
  • Me: *shows picture* LOOK AT THIS HEIGHT DIFFERENCE OH MY GOD I AM DECEASED
  • Friend: ...?
