I love this mangaka , her works are always my frvt I saw it on her twitter thanku I have seeen info there is volume 2 ,
Edit - it's wonderful story I it's age gap but the way even the written letters can express a lot and quite place can make you feel better I m touched by story so beautiful it's just seme almost kiss against his will so he understood and then he said he won't do anything but seme loves to come to his placd cuz it's quite and away from toxicity he was feeling outside then both of them were sitting on exist door and enjoying their time in front of door it's just so normal and cozy , wonderful I love this MANGAKA cuz her characters don't have kido faces but long and mature faces I m happy she didn't change her artstyle .
