I seriously cannot stress how much I love this manga. I think what it does so well is take the saying, "the more you seem to change, the more things stay the same/the more things seem the same, the more you seem to change" and executes it so well. Likr has the relationship become so comfortable and routine like that it's become mundane, and you feel yourself change? It's conversations this manga has throughout that it makes it so gripping for me.
