Ignore the title and trailer. It's a solid 10 Slice of Life drama with bomb chemistry, and a healthy relationship where mains communicate their issues openly and maturely, a character's trauma-related PTSD are actually part of the plot and not taken lightly (there is no magic cure, he is still in therapy until very end). The fight and sex scenes are actually decent and "believable" because the MC/Min is a supposed to be stuntman/bouncer who is trained to fight, and not some college boy who is suddenly an expert in martial arts when surrounded by thugs. I know everyone says ML (Q) is basically a damsel in distress, but he is a civilian who is caught in the crossfire between his "Righteous Hero-Cop" dad and the criminals he is pursuing. The guy isn't trained to fight, he has severe PTSD from watching his mom get killed in front of him and he keeps getting kidnapped and hurt by his dad's enemies. U can't really blame the guy for not really being excited about it.

Also, most viewers here underestimate how much your "fight and flight" reflex can be conditioned in case of frequent threats. For eg, if you are "fight" person, your first instinct will always be run towards the threat instead of away, because your mind honestly believes that u can fight it, whether u have the body to back it up or not. So, Q finding himself in situations where he gets in trouble because doesn't have the physic to back up his "fight" instinct (i.e confronting criminals, or running towards the gunfire, even if he gets panic attacks at the sound) didn't seem as weird or strange to me.

That said, all the introduced plot-arcs actually do get completed (some take until the end of show, and there is a time-skip in between); no character, INCLUDING minor characters, is wasted; no unnecessary drama between main leads, or with the dad. ALL communications happen openly and on-screen. The dialogue is at times cringe-worthy, but u can always stare at Ohm (whoever was in charge of his styling deserves an Oscar and a Nobel prize, because MY GAWD!!) and ofcourse, the OST. I'm sure even the people who hated the drama love the OST, so I won't waste my breath on it.
