BL which showed the process of both main characters falling in love in real-time, not someone suddenly came around and turned out he was already in love because of this and that, or one was secretly in love for years, or all of a sudden one of them was just into the other because he was supposed to be.
Reminds me of the story when I slipped away from my house as a child because apparently I liked to wander around and was brought home by a stranger. Now that I think about it again I'm so lucky a nice person found me lol.
