I focused on someone in OW2 without realizing it ( ⚆_⚆)???

Ok so, i was playing Overwatch in Rankeds Diamond 1 (I am Gold 3) and while playing as Bastion in the map Paraiso, we were 0 to 1, we played as defense in the round and although they got the first checkpoint. My team and I were quite resistant and I was one with more damage in the game, the thing is that without realizing I eliminated several times the kiriko of the enemy team and this seems that annoyed her because after killing her about 3 consecutive times she wrote in the chat: "what an imbecile your focus" and I was confused wondering if it was me she was referring to or someone from my team and after killing her 2 more times she changed to Roadhog, and that's when I realized that I made her focus without realizing it (bc she was only targeting me) and when I realized it I did what any human being would do, yes, I FOCUSED ON HER AGAIN UNTIL SHE WENT TO RAGEQUIT XD. After that she dropped out and 4 more dropped out of the game leaving only the dps, and if you haven't noticed yet, we won 1 to 2 LOL. (Also that kiriko told me to kill myself and it was very aggresive, but it didn't do much good in the game, so... L Kiriko KEKW).
