I am way too late for this, but let me enlighten you...
The answer is... NOPE. Horikita is barely putting up with Sudo, just for the Class D to survive and reach Class A, with the help from Ayanokoji, of course.
It seems the 3 idiots are eyeing for Ayano's girls.
Sudo is obviously going for Horikita. Honestly, she would care less if he just disappears. It would make her life more easier. Besides, she is slowly falling for Ayano. There are signs of her showing affection for Ayano i.e. blushing around him etc. We will know how this will end.
And the other 2 are going for Kushida and Sakura.
Kushida likes Ayano and she, alone, is vulnerable towards him, to the point where she feels comfortable to reveal her true self. She just wants to be friends with everyone, and the idiot is mistaking it for love/ affection. lol <.<
Sakura, on the other hand, rejected the idiot's advances towards her. We all know she is deeply in love with Ayano, and feels much "safer" around him.
