It was interesting at first but when her friend came around it got totally shitty in my opinion. The plot armor is strong, I mean just because she learns to dive and swim she then ‘accidentally’ finds a secret place that can grant special armor and skills. Then there’s the part with the MC that doesn’t make any sense. She levels up and puts all her status points into her defense and yet her hp is still the same. The MC is a dense loli, cute, OP and she has a fan club. She’s pretty much a mary sue but then her friend came making the story about TWO mary sues.
Nah, not worth my time.
