Elsewhere the full blame is on the cheater (or your own, if they cheated on you because you're a douchebag, but that's a completely different case).

So Sekai is far from blameless, yes, even more so with the circumstances. This meaning not that I feel any sympathy for Makoto, but rather that not only she's their friend, but also hooked them up.

However, the main person who should be worried about not cheating is -still- the person in a relationship...and that's Makoto.

You speak the truth. Sekai's also to blame, but the responsibility ultimately rests with Makoto.
