MAYBE A REREAD?

Don't be trying hard to make this BL make sense. It's just a toxic soap opera, which is so bad that it's "good." Absurd twists, stupid plot, annoying characters, and the MCs end up happily together with 3 kids. 3 stars because I really enjoyed it due to its sheer soap opera quality.
