I am also looking for recommendations like this.
The only one I can think of is "secretary jin's confinement diary' which has a fairly different plot but some parallels in that it's about a guy who confines the other and the confined one really likes/enjoys it from the beginning. I think you'd like it if you like this one! But they are different.

Can someone recommend me similar manga/manhwa like this?
