I like this new series! The first chapter felt like Sho finding his 'Momo' (with additional black cat) And after reading this it seems to me like Jun was either abducted or has ran away from a hospital or something. Well either way, his unknown background is very mysteriously interesting.
I love how Sho seems smitten right away lols (and Nagase is telling Sho to keep Jun is a plus)
And the part where it was Ohno who lures Jun to communicate with him first was making my heart melt (ah my jimago heart XD)

Thanks for the update XD
