This is one of the best BL with Kid story out there! Definitely recommended. Both MLs don't just meet in the first ch and fall in love magically and this story is more focused on feelings between all 3 of our MCs. Honestly I am so surprised by how good this story is. The Kid too. He's awesome. Just read it! The romance developed is also handled so well!
I love how the Kid is with both of them. He has his own personality. He just doesn't randomly treat the LI as a parental figure. Honestly even to the end but still you can see that they are a family. All 3 of them.
