johnny and you have been good, you've been friends forever and he just recently discovered his feelings for you after breaking up with ali. Sure hes always fake flirted, but you've always assumed he was joking.. But watching you laugh and learn kata's with larusso his enemy made him realize just how much he cared about you, when you wouldn't learn with johnny because you didn't like cobra kai, it made him terribly jelous, but he couldn't do anything without revealing his feelings to you.
