Short review:
Slice of life that you would have thought it's just another typical harem anime, not it's not. It has tragedy time travel and romance.The first episodes will confuse you what the heck is happening then as you continue watching, the story goes like nothing happened. It all made sense later on and the anime ended with a conclusion which I guess is good.
Pros:
- unexpected genre shift
- characters are likable
- the drama is alright
- no bullshit like fanservice, fillers or other nonsense
- it has a conclusion
Cons:
- everything in this anime is nothing new, as you've already saw in other anime's
- visuals looks outdated, like the early 2000's animation
- slice of life element may bore you
- execution of the story is not done well
- you may find the MC's goal trivial
Overall it's a worth to watch. Not the best in the time travel genre as you can find better out there but it's still good.
Final Verdict: 7/10
