What I love so much about this story is that while, yes, it is mostly about you and Cove, the love you have for your family and friends isn't lessened in any way, and in general, the game shows that platonic and familial love are just as important as romantic love (if not moreso sometimes!). Usually when I'm playing a visual novel type game, I'll just focus on the romance option to the exclusion of all else, because the game is set up that way. This game, not so much. While there is still a TON of sweet and amazing moments with Cove, I'd also find times where I'd reach out to my sister or parents for support instead, and the scenes were JUST as heartwarming and full of love.
I love that you can be any type of person and as long as you're not like, cruel, your family and friends still love and care about you. And even then, just like in real life, you can be cranky at times and still be forgiven. There's no such thing as the "right" dialogue option, you don't have to like all the same things Cove likes in order to maximize relationship points, you can just chose to care about each other, and be yourself. That's enough :)
The writers also really capture what it feels like at each stage of life, the way kids think, their logic, their mindset, their speech patterns etc. The best-written child characters I've come across outside of famous children's stories like Junie B Jones, and I loved watching each character grow and change in a realistic way.
This reminded me of things I had forgotten about my own childhood, it even made me reach out to my former neighbors who I used to play with every day. I hadn't spoken to them in years, it was amazing to see them again (even if it was just over zoom) and I have this game to thank for that.
