Takeda is so boring.
Why is he popular again? For being a "good guy"?

It's more along the lines of everyone's shittiness, his is the most implicit; and that of everyone being screwed over, his is the most sympathetic.
He think dating is about sex, which is a red flag in of itself. Forgivable since he's in high school, and shoot, that's what high schoolers do: screw up by their naïveté in the romance department. But doesn't change the fact he's so easily persuaded by the notion Yuma might be cheating on him. If you can't trust your partner, your relationship is about as deep as a puddle of water.
