``Out of everybody, why him?!```
The very first words he said to you after you casually let it slip that you are going on a date with Rukawa.
Hanamichi is overprotective of your feelings, he always has been involved in your business, even before adopting the delinquent lifestyle. After that, It's safe to say he was more than interested in the events happening in your life, including your love life, which was especially annoying. Hanamichi doesn't feel a twisted jealousy, nor does he think you're his innocent, adorable sister who is helpless. Quite the opposite—he has seen you throw some mean "playful" punches and Indian/Chinese burns.
The root of his interest is curiosity,, he doesn’t know when to keep his nose out of your business, which causes a few quarrels between the two of you.
The problem arises when Rukawa involves himself with you. Hanamichi has seen how Rukawa treats women, especially those who are interested in him, which is why he might seem overprotective when all three of you are in the same room. In reality, he's just worried about your heart getting broken.
It also helps that your relationship changes the dynamic between the two boys. It’s not a noticeable change in their behavior toward each other, because you’re still forced into the role of a mediator when Kaede visits, however they do try to not physically fight and compete in front of you.
Hanamichi doesn't care to give an approval because he believes that it is not needed and you can make your own decisions without his intervention and Rukawa tries extra hard to embarrass Hanamichi in front of you if you happen to be in the gym when they're practicing.
On the surface, nothing changes between them, except maybe they try to avoid throwing punches at each other's face. Only the face is prohibited... They don't want you to notice bruises and be mad at them...
