Man. It's just my opinion, but that ending kinda sucked. 5/10 series, I liked the characters, but the story and character development just didn't do it for me.
I really like this set up, especially all the side characters. EVERYONE but Oga knowing that Umeko is trying to go out with him and doing all they can to support her is the best.
I love her so much, she's such a little asshole. She just can't resist the urge to tease people, and it's even better when someone pulls a reversal on her. Whether it be Sasaki with his unawareness, or the manager throwing it back in her face.
Love Yamada dropping that "SIR" at the end, really saw him get in another girl's lane and was like "Who told you you were allowed to be checked-out by someone else?"
I still can't get over Sakiko getting scolded by a random girl, immediately deciding "This is mine now" and then proceeding to do everything in her power to keep her happy and at her side. I love their relationship so damn much.
