I'm going to pray that MC and the general stay as a found family, brother-sister relationship. Someone tell me if I'm wrong before hand so I can drop this before its too late.

It's good. Like reallllllyyyyyyy good
I'll break up my thoughts into different sections to easily organize my thoughts

-The first couple of chapters genuinely made me shed a tear. Yostuha is so kind to Uichi and easily brightens up his world. The constant positive reinforcement and reassurance that she's happy and okay is so nice to see.
-Yotsuha is so fun, she's taking everything seriously and doing everything she can to help Uichi, but is absolutely weak to him at the same time. Bestieomg yuor such a simp I love you
-The time travel powers are also interesting, every turn of the crown turns back time to the day before at 20:15 specifically (why so specific). There seems to be a cool-down period of sorts? The clock will rewind itself to the appropriate time, but you can't use it during the rewind process. Good limitations and solid power, I like it.
-I kinda like that they're taking death a little more seriously in Yotsuba Clover. Like, yes, Yotsuha could kill all those who made Uichi suffer, but then what? Uichi would probably think that he's killing all these guys by simply being around them and that he's a bad omen, then just spiral from there. Getting everyone in line is a better plan since it'll give Uichi some blissful peace of mind and Yotsuha some more pawns. It's common for revenge stories to take death to the extreme, to the point where it's not even taken seriously anymore, so it's a nice change of pace.
-I like Fuu, but I get a bad feeling from her, maybe it's because I read too much manga, so PLEASE PLEASE PLEASE DON'T BE A SECRET BAD GUY AND JUST BE THE GOOD BEST FRIEND CHARACTER PLEEEEAAAASSSSEEEEEEEE

That's all for now!! Thanks for reading!! ヾ(☆▽☆)
