I'm glad others don't secretly hate Tadano or something. "He's a good guy" is still putting it mildly, but... it's nice. The best part is that Tadano wouldn't get a big head if he heard that either; he'd just laugh it off and go "Oh! Thanks!" while rubbing the back of his head or something.
Either way, we're finally getting close. I'd give it... two or three chapters; the next one seems to be about boy talk and I think the next one will be set up, possibly ending with the confession and most likely with fireworks. Gotta go for that cliche. But ultimately... I'm scared. ;-;
Not of what Tadano may do; at the end of the day, he's a sweet heart. He'd never intentionally hurt someone. But... while he likes Rumiko... It's clear he likes Komi more, but he'd also hate to hurt either of their feelings and still feels that he doesn't deserve Komi, even as a friend, despite all the evidence to the contrary. Ultimately... someone is going to get hurt, no matter what Tadano's reply is, and that's awful.
The Harem/Triangle romance is still possible, though..! Fingers crossed to avoid heart ache!
