Read this yesterday, hehe. You already know my initial thoughts :D
Now for the rest of them:
I actually like the writing and how everything is straight to the point, it makes the plot really clear! There aren't any extreme descriptions, which I see a lot in other games and deters me from reading. So looking past the grammar, the writing was amazing in my opinion :D I liked the funny moments too between the characters, like when they went to the cafe lol
On a side note, I love looking at crabs too XD, I pick them up and stack them sometimes. The beach setting was very nicely done and I think it's cool you got to go there during the summers!
As for the endings... I love both of them for what they are meant to be. Admitting your feelings to someone can be really hard, but it's even worse when you're never going to see that person again. I think it's a good lesson for anyone to say something before it's too late. Thank you for sharing the story and I hope you're doing well now :D
