I gave up trying to make sense of all the threads. Similar series that weave different timelines and hypotheticals played out in real life, use different color schemes or blurred screen edges. This is so confusing to follow, despite the dates designating the past, there are scenarios being played out that don't fit in the "present" timeline and what is real and what is a fictional trial or the things that happened leading up to that trial - or someone's imagination of what could have happened - it's a mess. At some point a convicted criminal that served out his sentence is questioning the male lead, who's also under suspicion with police watching the scene. Why would that happen? Was it also a hypothetical? Is this a custom in Korean interrogation? If you can make sense of how it's portraid, then it probably is worth the watch, because I do like how the male lead is obviously framed for a murder, with almost no way out.

It started off good until we had the first trial involving the first student. The drama didn't do a good job laying out the information in an effective way, but rather delivered it in monotonous big chunks. I didn't find the cases appealing. The pattern became clear after the second case. Cycling through the students while revealing more of the main case along the way. Somehow they made everything and everyone very conveniently connected to the main case. This resulted in an over-complicated mess for the sake of building something grand and complicated. Despite of their attempt, they also created too many plot conveniences because they had no clue how to progress otherwise. The students' personal stories weren't good to begin with and cliche at best. There were just too many shortcomings in the writing department to count. The cast was okay but there was a lot of overacting going around, exaggerated expressions, motions, phrases and unnecessary edge-lord-like quirkiness. You may think the professor was the main character but shortly after, he became a support one. Some episodes passed while barely saying any lines. The director was trying his damn hardest to patch up this hot mess. If he were to be replaced, the drama would flop so damn hard. Thanks to him we got something kinda watchable.
