Tbh Leo is selfish. But his ego isn't that massive.
He never puts others down nor talks bad about others. He doesn't even lash out when someone points out his flaws or calls him out for shit.
Being selfish is different than having an ego.
If Leo must make a decision it will most likely come down to his feelings for JJ...and his feelings for racing itself. Which we have seen are tied together as one.
So in the end...if this conversation ends badly...which it most likely will.
Leo will most likely become truly heartbroken and drop racing entirely. (Probably will go back to modeling...or if current events continue. Become depressed)
JJ will feel heartbroken as well. But in his stoic attitude will just leave Leo and move on in his life while later having a reason to feel guilty. Only to realize he fucked up as well and will try to reconnect with a man he has broken.
We will probably be sent on some angst laps just like a race car ironically XD
Eh, I do think Leo has a bit of an ego. An ego doesn't necessarily mean that you outwardly treat people bad, but we have seen Leo looking down on other racers (not even remembering their names). He does react strongly to others talking negatively/criticizing him (not punching ppl or directly calling them names) BUT inwardly he reacted strongly to JJ criticizing him when they met. Leo has an ego, but it doesn't mean he's an asshole.
My deal is that Leo's ego won't let him admit he loves JJ because "ew cringe, I called him my fortuna ew". Even his recent conversation with JJ focuses on how it will help Leo with his racing because Leo can't outwardly admit he loves JJ and needs him not bc he (JJ) is his fortuna but because he misses JJ and wants to fix their relationship. In the new chapter, Leo would rather ask to be fwb than admit he wants JJ back. Leo didn't call JJ during their breakup and even tried to find hook ups bc he wanted JJ to make the first move to avoid admitting he wants JJ back. He blames losing his fortuna, not losing JJ's love and support, for his "bad luck", which is not actually bad luck but it is him both not taking care of himself and not listening to others about the race.
Sorry for the late response!
The crash itself was a wake up call for Leo, but Leo is still not ready to admit it. The crash wasn't deadly but it came about because Leo refuses to grow up. He's not taking responsibility for his own well being, physically or psychologically, because he has been so reliant on JJ. Now JJ is not in the clear because he did not communicate all his feelings, leading to Leo continuing like nothing was wrong, but JJ is right when he called out Leo on not being 19 anymore but still acting the same. Leo is a grown ass adult, he should be able to rely on himself, especially as a professional in his field. He let himself go, continued clubbing, let his ego win over reasoning, leading to his crash. He was lucky nothing serious happened but he put blame on having lost JJ (his fortuna) rather than his own lack of self-care and self-control. He's gonna receive another wake up call from JJ however.
I believe in his conversation with JJ, Leo will express regret and try to artificially repair their relationship. He may even call JJ his fortuna and outright state why he wants to get back together, which WILL anger JJ. So far JJ has wanted distance from Leo, not because he loves him less or bc he got a better offer somewhere else, but because he wants Leo and him to have a better relationship by being able to grow as individuals in a relationship. So far it seems Leo gets more out of the relationship than JJ, we see it in the first chapter where Leo has sex with JJ but only receives his own gratification and leaves JJ on his own (High and dry). JJ also strangely seems to not be completely bothered by the idea of Leo sleeping with others, and while I assume it may have come from a misunderstanding it seems that JJ doesn't believe that Leo really loves him. JJ may believe that their relationship is more transactional than it truly is, and that's why he questions if Leo has ever seen him as his boyfriend. Thus, Leo coming to talk to JJ about JJ being his fortuna (rather than someone he loves) may cement the idea that Leo does not see their relationship like JJ does. Ultimately, JJ might leave and Leo will have to make a decision - his ego or his relationship.
