The novels of both of them were already completed and published at 2009. The adaptations are released simultaneously but just recently. In my opinion, Passion Raga is my personal favorite of the two.
There are about 5 books of Passion saga :
Passion 1-6 (Ilay x Taeui)
Raga 1-2 (Xinlu x Yuri)
Diaphonic Symphonia 1-5 (Ilay x Taei AND new couple Richard x Chris)
Suite side of Passion 1-2 (Domestic Iltae)
Side of DS 1-2 (RiChri idc actually)
Suite complete works 1 (vry funny Iltae)
Holy Passion - final (bonus) (Awwwwww love Iltae here)
And yea.. We're about to reach the end of Passion, but still 10+ volume to go before its real final. Lmao. (Damn I need moooooooore!! Rawwwrrrr)
can someone explain why there’s a manhwa abt xinlu but this manhwa isnt finished yet? Also same author? (●'◡'●)ﾉ
