To be honest, i wouldnt call this story a BL. I mean, you can feel the love, emotions, between characters, but it is not definitely romantic kind of. They felt more like a family than lovers
And im not saying its a bad thing! I loved the story, its really heartwarming and relaxing one. Art is also pretty and clean. If youre looking for good, wholesome story, thats not exactly a about romantical love, then its really for you.
