I guess Momo, Suzuki and maybe Kiritani tried to save his face at the party and during this last week. After all they are popular and people may listen to whatever bullshit they spit in order to keep up the mood of the class.
I wish I could see it, but this is story has Naoki's point of view and we can't know what happened in the class room while he was being an hikki.
Now that he's found his rebound with Momo, he'll never realize how truly horrifying was the conversation he just had with Midori.
I had to cringe a few times.
Naoki from the start of the manga would jump off a building if he saw this conversation.
