I feel like the FMC's friend is better for MC and they talk a lot too after their seating arrangement changed

Wataru:Our dreaming boy MC, due to his family constantly negging him even as a kid he was trying to find his place in the world. That led to him acting like a class clown in school just so he can mask his self assured inadequeteness. After a brief encounter with his goddess who champions him against some rude students he ties his worthiness to gaining Aika's favor. Which leads to him obsessing over her and acting like her manservant even up to this volume. The inconsistency of this character lies in the fact that when it comes to intrapersonal relationships he is actually way too competent to fail to notice how people around him feels. You can clearly see it when he drops the clown charade and gets serious just like he did with Sasaki in the latest volume. He should either try to get Aika actually open up to him emotionally so he can resolve their complicated relationship or completely remove himself from the equation so he can move on. This inadvertant push and pull game he's doing is working wonders against Aika but she's too timid to actually take a step forward and Wataru is acting too clueless which leaves them in the limbo.

Aika:A sheltered girl who is smart enough to excel academically but also dumb enough to not to notice how other people feels about her. You can see it in her monologues how she's always surprised when people pay attenion to her the most and waives it off as if it has nothing to do with how attractive she is. Since she is this emotionally immature you can understand why she shut down Wataru since the unknown can be scary but for a smart girl like her you'd think she'd have some introspection on what she actually feels after almost 2 years of getting chased by him. But no, she completely dances around the topic and tries to pull back Wataru whenever he starts pulling away.

Kei:Aika's best and probably only actual friend. It's kinda surprising how she's been called best girl for Wataru when actually she doesn't really care about him. All she does is in favor of Aika. Like she manipulates Wataru from breaking away in the beginning by accusing him of isolating Aika which is kinda fair but after half a year and reinstating Aika with her classmates she still tries to bind Wataru because Aika needs her emotional pillar. Not giving a f*ck about how he feels. She's only in the story so Aika doesn't have to take agency when it comes to Wataru.

Kaede:aka gorilla sis, possibly the cause of Wataru's self esteem issues along with her mother. I have 2 sisters and while we do tease each other a lot it's never in a malicious way like it's shown here. Violent tsundere sister is really not working author. I don't like her character even if she's mellowed out after the rooftop match.

MC (Wataru) : Everyone seems to think that the protagonist is a big victim who is deceived and mistreated by everyone, including his family. What I disagree. The MC is a clown-type character, so he makes jokes and says absurd things (you must have met people like that), so he usually has a teasing relationship with everyone. And he is also to blame for the current scenario, since he was practically an FMC stalker and walked away from her without saying anything. His attitude towards FMC was insane, if you saw someone like that you would definitely find it creepy and rightly so.

FMC (Aika) : Aika has a very interesting development, where along the way she gets better and it's explained why she is the way she is. I see people think that she is a demon who always treats the protagonist like garbage, which I disagree with. She really sucks in volume 1 and the beginning of 2, as she's completely confused by what's going on and doesn't understand anything. For FMC (and everyone who knows them), MC was part of her group and rejecting her confessions was part of a routine, as if it were all a joke. Yes, she was insensitive and didn't take him seriously, but she didn't do it out of malice, but because she didn't understand anything. And after volume 2, apart from when the MC embarrasses her, she is almost always kind and cares about him, and takes the initiative to talk, so it's not like she treats him badly all the time, it's the opposite.

Sister (Kaede) : Another character that everyone thinks is a demon and I disagree. Her relationship with the MC is pretty normal for teenage siblings I'd say (must have more background, as vol 8 indicates), unlike people who say it's toxic. It's normal to fight with your sisters (I have 3 sisters) and it's normal for the oldest to boss the youngest. Kaede since volume 1 despite being tough with the MC, she is always worried about him, so much so that everything she did at school was because of him. She has anarchist tendencies and is very difficult to open up to, which causes problems, but even so, she always tries to take care of him, and this is shown from the beginning.
