I strongly doubt that'll happen. Glasses-kun is probably gay, which is why it's so easy for them to talk with one another. Just look back at this scene:

"You got a call just now. I didn't answer it."
"Did you see it? The call screen."
"I did, but I'm not interested and I won't interfere with what you like."
What could a call screen show that would be enough information to want hidden? Certainly not "Mom", "Brother", "Pete's Pizza Place" or "555-5555." It's enough to indicate "what he likes," and prompts an immediate assurance from Tachibana. For example, what if the call came up as, "Boyfriend"?

Hm, now based on this page:

It seems like he might be a lolicon instead...
