The progression indicates Chris most likely. Yet, Jake may have a shot given the right circumstances. All I know is it will be 2027 before we find out.
Likely and I won't write another dissertation on the topic but if this dev fucks their pace up to pull a AWAM/L&P I'd sooner stop reading this VN.
Forgetting the time between releases for a sec, the pacing of this plot so far wouldn't make sense for them to suddenly start milking and doing the "each of the 12 men proceeds at the same pace" BS. It wouldn't be realistic or what this story has been so far. It would be like a totally different story and for the worse.
Then we have to account for the development time, too. JOHN is an example of a story that has decent pacing but each update takes so long that when she eventually fucked it was very anticlimactic.
So pulling an AWAM and having slow updates as well as a slow pace of story is a recipe for nobody giving a shit anymore.
