I remember reading " Dating a team magma grunt " years ago. Checked the link for an update, and it turns out the author abandoned the series and nuked all their work. Army life probably made him lose interest in the series. It's too bad.
EDIT: Allegedly the author is working on a webtoon under a different pen name.
For the work itself, it's alright smut. Not too often you see a rapist use protection throughout the entire work. 90% of the time they don't care about that.
