Now I do agree with you. In ep 4 Makiko is actually being used as a tool of temptation to clearly show the character differences betwen Junichi and Keisuki, one is a great character not cheating neither his gf nor his first love, while one is evil, cheating on both his current and ex wives. With Naota occuping minimal screen time he probably won't be the main culprit of this drama, while Keisuki is likely now. I can't recall the exact details of what happening 23 years ago and Keisuki probably cannot be excluded from being the possible killer too. Might be the brother of Naota knew some secret of Keisuki causing his death.?
In defence of Makiko now knowing her loved one no longer available she is within her right to do anything with other single man, as long as not cheating.

I can only think of 1 possibility that Junichi likely the killer of the rober 23 years ago (not a punishable crime now but still a crime, although morally probably right), which caused him to put a stone wall surrounding him, especially long relationships with women.
Also read a press release that both leads are not totally upright, meaning they both done something in grey areas.

Basically agreed totally with what you observed, but with the long wait for next episode just add a bit more of my opinions as this is my current favourite drama.
Ep 4 is short only 45 minutes long and it spent most time in the character description of Keisuki, Makiko, and a bit of Junichi and his gf, that's kind of minimising the probability that they are the killer of the shop owner. The quadruple love relationships is all laid bare here too. Makiko's getting physical with her ex is a kind of reaction to her huge disappointment that her chance of a future with Junichi is dashed totally, and imaging what Junichi and his gf would be doing living together. But with 6 episodes to come, this likely would setup the stage later for the 2 leads to get closer considering the drama description with the detective ml meeting his first love in a criminal case ( but this need some dramatic events for this to be possible). But as a jdrama, ending is never predictable.

So far it is a perfect blend of murder mystery with kind of controversial romance (multiple relationships, detective vs his suspect etc) in the background.

Up to episode 4 the drama spent lots of time in detailing the character of 3 of the 4 friends. Junichi seems the most morally upright with him bringing his gf in meeting with Makiko and her son, and not going to dine with her afterwards (even though he might be the one killing the robber when in grade 6, early teen). Makiko, as a single mid 30 mother, only cared about her son and man relationship, approaching Junichi whenever possible even though he is the detective in her case. Keishuki very much consumed in competing with Junichi and, why should he murder someone for his ex wife while he already remarried? All 3 seems not fitting the profile of the killer in current time.

With romance part of the genre in this drama there has to be romantic tension between the 2 leads. No idea how it will end, happy or tragic.

As predicted. That could be the only possible explanation why he stopped approaching Makiko afterwards with guilty feeling. But nothing is for sure with this drama's twists and turns.

Remember this is a murder mystery, a thriller with unpredictable twists and turns. Usually the most obvious suspect ends up not the guilty one, while the most unlikely one is the one. There is a chance Junichi killed the criminal 23 years ago (it is too long ago so he won't be charged now) and thats why he has been avoiding seeing Makiko afterwards, only watched her from a distance.

Unless reading the novel hard to predict how this excellent drama (so far) will go. By episode 3 seems romance is part of the genre and remember the 2 main leads are Junichi and Makiko.

It is not the normal type of romance plots at all. Their relationship built-up all about trust, which is the key requirement to solve Da Wit's own case, nothing more.

The main plot of the drama is the case of Da Wit himself. It is very very carefully planned. From the conoloscopy of Da Wit, which started from beginning of ep 6, to epilogue of ep 7, leading to the discovery by Gi Ppeum that Da Wit is innocent, the drama always planned for her helping him to prove his innocent. It is the most exciting, satisfying climax of the whole drama, the heroine saving the hero of the drama. One can now concluded that the hand holding the apple of temptation in the poster is that of Oh Jung In. For those who shipped her with Da Wit read below for the romance line:

Totally agreed. Also way better than Beyond the Bar

One can only hope so. With such a tragic past of the ml, a drama cannot allow him keep living in the shadow of the tragedy, even after a year of time jump! And thats the contrast of Pro Bono, that Da Wit grown from the dream of a top judge and his promise to his mother, to someone who focussed on helping the disadvantaged, and the pro bono team

One Dollar Lawyer great until the last episode, which all of a sudden reversed all the growth the male lead achieved (after the murder of his previous girl friend), and back to living in the past, and ignoring all the needs of the other members in his law firm. Very disappointing.

David a man. Snow White ever sinful before and after eating the poisoned apple? The apple box is where the story began, and then David vs Goliath episodes followed

One forum pointed out the poster of Pro Bono has an apple in front of Da Wit, with the apple being held by a woman's hand if looked closely. Very much Adam and Eve implication. Whose the hand belongs to? 2 more episodes to review.

One can make multiple interpretations of a well conducted scene of a great drama. Say the last few minutes of ep 10 when Da Wit is on the stand facing Gi Ppeum, if watched carefully, they never left their eyes off each other and their dialogues seems just between themselves. Even when Ms Oh said all the accusations are suggestive and the judge agreed no need to answer, the world around them seems disppeared with Da Wit answering straight to Gi Ppeum, except the moment when he admitted guilty towards the judge. And ended with locking eyes till end of episode. This is real high intensity, that you can make whatever interpretation you wished.

On the side of the pro bono team at ep 10 they are just doing their job as lawyers. They are forced by the CEO to take up the case against Da Wit. Lawyers are trained to provide the best outcomes for their clients, within the boundaries of the law, whether the client is a criminal, murderer make no difference. Morality, right or wrong, are not taken into account by the law, most often. In fact Gi Ppeum is put into the worst possible position in this conflicts between law and morality, as the accused saved her family in the past and now she has to put him into prison. This is called a drama.

2 women in the last 2 episodes whom Da Wit, the hero of this drama met personalily. One comfortably, whom he knew for a long time and he quite understandings her, no drama, on the same side, one wins both win. The other full of emotion, conflicts, wanted to tell all the truths but that can only bring more misunderstanding, lots of unspoken words, just full of angst, and if she wins he might lose everything. He is reflecting all the emotions of not having her trust very much according to epilogue of ep 7. But at the end he put his fate with the unlikely one (seemingly, for sure more twists and turns). A great great drama, but this is a common trope of kdramas to show the significant one. I bowl to the acting of Jung kH, reminded me of his hard luck love story in Hospital Playlist.

There are some attractive photos of the main couple of Pro Bono on a December issue of a Korean beauty magazine. So the production company has been promoting it, no secret.
