Although I agree with
@Entryhazard about Tendou's state of mind, I agree with
@Purplelibraryguy, or, more precisely, I don't care at all what happens to Tendou. Announcing that she was in love with Yuu was a jerk-ass move, regardless of the reasoning, since it was a bald-faced lie. She's been the 2nd least likeable character right from the get-go. She's had it rough, you say? Oh, sure, but there's lots of people who've had a rough, miserable life but rise above it all and don't cop such a negative attitude about everything and everybody. I've got no sympathy for her.
