Star Child's manga / #Fader sun relationship(1)

This is could have been so much better, the setup for the if the story had sooooooo much potential if explored/expanded on all the relationships like the fader x sun or sun and dead mum (did he cook whit her, was she a good influence on the dad? Is she the sun roll model??) and like as a minimum a chapter on the fader reaction to them dating and all I think it would have been nice and in line whit Nishida back story to let him (the sun) know that there is a fine line between stilling kisses and harassment (I know the kid his honest and all but a missed opportunity for his character growth …) And I personally think that it would have made more sense if Nishida was the one being “let’s take it slow” at the end of the day he was the 27 year old man… I could see this story in a mini series… but too many plot holes ahah and at the end of the day is fictional…
