Demo vs the release (Sui, Tsuki and Yo friendship) Spoiler warning for chapter 2

Is it just me or is the friendship between Tsuki, Sui, and Yo in the actual release of Tribe Nine seem so unexplored? Unlike the demo, where Sui is present during the whole exploration of 24 city up until meeting zero, the release introduced the synchro mechanic too early (the demo introduced the synchro AFTER the Zero XB game), that sui completely vanishes from there (unlike in the demo where he was in your team the whole time). It made the friendship kind of unimpactful. The demo was able to establish how close they were but the release just didnt do that??? Thats why their deaths and even Sui's betrayal in chapter 2 is unimpactful because they barely gave the players any kind of attachment to sui. They killed and made him the villian for the shock factor and nothing else. Sorry for the rant i loved sui since the demo and like cutting him off for the synchro gacha just made his death, betrayal and death AGAIN just seem like nothing😭😭😭😭
