Guys, I just found a gem in wattpad. A transmigration novel titled: Pick The Second Male Lead. So many arcs with different second male leads but it is hinted that all of them shared the same soul. Under the same author (harui30) on wattpad, she also just finished book about transmigration titled Calla (Book I and II) and Rebirth of Fa Wei Lan (Book I and II).
Try it! I slept at 2-3am for the past three days reading this author's novels.
