Review of Sing "Yesterday" for Me

The slice of life kind of storytelling was okayish at best, but the ending was horrible, or at least feels unfinished, I elaborate down below, at the very bottom, but with spoilers. The characters were written well, except for the mc, so I was expecting more from the anime. But that's the only positive thing I have to say. The story itself was driven by pure stupidity half the time which is a shame. I understand that the story needs *something* because of the slice of life nature, but this is not it. The art was okay at best, fits this bad anime if you ask me. ---SPOLER ---

The ending is just soooooo bad. I'm fine with the idea of Shinako and Rikuo are not meant to be, their "relationship" was honestly awkward so I didn't mind them backing off and agreeing to be friends. But tell me why it was necessary to then pair them with their obsessive counterparts in the last minutes of the show? Even the show made it clear that Rikuo is only taking Haru out of selfishness and just wants to feel loved, and Shinako only takes Rou because she sees his dead older brother in him. Both are horrible relationships and there's no "punishment" for that, the show just ends right there. There should've been 1-2 more episodes showing how these 2 relationships inevitably fall apart so at least there's a takeaway, but that doesn't happen. What a horrible ending
