I think I loved Valle the best. He has such a good character background, is such a good friend in every route, and really sticks out as the best partner to me. I love how the characters interact with each other. They aren't over the top and are instead written like real people.
Sekheo was written well (a little dramatic in the end but it all made sense well enough). His story was good but I think more time researching with him would've been nice). The MC is a little pushy in his route but not usually overly so. It is an understandably sad route but with good bits of character building and fun.
Valle was the best IMO. He's super understanding even in everyone elses routes. He's a pillar for your character and supports the MC so well. Very interesting character I wish we got more information about but I get why it was short. Only issue: (Not sure why the MC agrees with him that their first date didn't go well? He has a demanding job. It makes sense that he had to go. It would be like dating a doctor or a police officer or something.)
Solis I played first and I'm glad. He's sweet but mean to Valle. He doesn't seem to understand that Valle is totally different than the other stars that stopped doing their jobs. I think we should've yelled at him more in his and Valle's routes. His route alone is sweet and normal with a little bit of a bitter taste because he's mean to your best friend. In Valle's route though.... He's a total butthole. And Valle is even nice to you when you choose Solis and still supports you.
Ranting sorry. It is a really good game and I love the art. The range of facial expression is really good and I love the chibi art as fill ins. Definitely recommend!
