watching individual circumstances kept making me think of to my star s2! similar plotline in terms of there being an ex who got ghosted and goes to find the other one to convince him to come back. difference is that in the case of TMS, the ex went to find him get back together with him while in IC the ex wants to make a movie with his ex's story. if you liked TMS s2 you would love IC, in my opinion.

The male lead is a older man with a different past life who gets put into a new world to try and make this other guy's life better, very similar to this story.
