I'm really enjoying this manga so far. It's honestly making me think about myself, and what it means to be an adult. While it has crossed my mind, I haven't thought much about what it actually means to be an adult. How you see the world differently. How the world sees you differently. The responsibilities and the freedoms. And how it's different for each person.
Back to the manga, I feel like while the MC is growing an learning, the endgame isn't them getting together. Maybe more so them becoming friends, and having more confidence in himself and what he wants in the future when he goes to college. Recognizing the difference between a crush, longing, lust, and friendship.
Not that I'd be opposed to them ending up together, I just don't see that happening with hoe this story's world is portrayed as being somewhat grounded.
