I finally got around to finishing Overtake -- many thanks to the anons (or maybe just one anon) who were recommending it so persistently in these threads. I really liked it, I thought it was very sincere and had a lot of heart. A very charming message about continuing on after life doesn't end up like how you hoped.
And also obviously Haruka and Kouya are great together. Their relationship is really cute but also has this slightly edgy quality, in that the show is presenting us with this credible age gap relationship in the middle of quite a natural and realistic setting, and Kouya is often so pathetic that Haruka has to act like a surrogate parent to this guy who's old enough to be his father. The same Haruka who has no parents of his own. And meanwhile for contrast we have pink hair and his dad as an example of a totally healthy and functional inter-generational friendship. It's a little screwed up, psychologically, which I enjoyed.
