This story is actually quite heavy, and deserves to have psychological tags because of endless SA. We can never hope for their relationship to progress in book 1:Passion, at least not until we reach Passion: Suite.

Not much, there won't be much progress for Ilay in current book. In fact, Tay had to endured endless SA/grape in the future. The manhwa censor some details, like there is one scene in later chapter, where manhwa removed completely the scene where Ilay choked Tay so hard because Tay mentions that he want to meet Xinlu to Ilay

Hope that when author regains their health, he/she will publish a side story that will tie every loose ends in the manhwa. Despite the rush ending, this manhwa still stand it's ground against most popular manhwa nowadays. The plot ain't that messy, just need to have a satisfying conclusion to Haegyung daily life aftermath, like his relationship with his family being repaired and a tiny bit more of what comes after Woojin and Haegyung finally settled in together.
Dead people receive more flowers than living ones because regret is stronger than gratitude.
RIP all the revengers. May Seo Chaeyoon also find peace one day. The MC despair is on par with MC from trace of wonder and I'm here to see their happy endings. ╥﹏╥
