i sometimes like these kinds of endings, the ones that dont need any explanation or clarification, since youve been with their journey, you'd know right away they dont need to spout clarifying words. They just grew together, feelings, needing one another and thats pure and love in its own way.
i really like adult romcoms, it feels more realistic, two adults just grow together and stick together and not needing any labels since they both feel the same way.
