no way he didn’t know he was wearing a couples ring-

He doesn’t know, he just assumes. Mc never told him. Go back and read the latest chapter. Read the dialogue and piece together context clues.
Mc said “that’s cause-“ so he KNOWS he’s wearing a couples ring. He’s shocked that the friend knows he doesn’t have a partner. In the earlier chapters Mc made up a name for his fictitious gf.
omg excuse me- this is crazy
