I think there would be some talk about why he left the childstar industry, and probably some talk about the disillusionment with the media and how he was becoming someone he didn't want to be- then discussion about why he would come back into the limelight with Robin. Probably some tortured backstory about some drama, because hurt and stuff, and then likely how similar he and Robin are, and maybe addressing the concern that they could potentially spiral each other downhill?
I love all these suggestions for Seth he's an enigma in the first place but I personally would like to follow that route should he get one. I got a new computer so I have to re-download the game myself but as I'm reading through this I noticed there's been some updates since I've last downloaded it so this is all a good thing. This really is like a visual novel that breaks the mold. When I first seen it I was like oh I have to have this and I liked the epilogue for the childhood friend and I was looking forward to other epilogues cuz I know that they weren't finished yet I hope that there has been epilogues added or there will be some epilogues added. All I know is don't ever be discouraged because you're a really good writer and you have a really good thing going and you should finish it the way you feel it should be finished because I think it's something you should be proud of. Because I personally am happy I just happened to find it even if it was by chance I'm glad I found it
