Well, it could have been Shizaya had Wachi been a more sensitive man and had reacted to Makio scamming him by throwing a vending machine at him. But I am so happy that this is my beautiful Shinra x Izaya.
Wachi and Makio, themselves, may not be entirely the same as Shinra and Izaya but their main emotional relationships are exactly the same. It's so fun. Wachi's love for Makio is very similar to Shinra's completely devoted (masochistic XD) love for Celty . And, Makio cares for Wachi geatly, maybe already loves him, in the exact same way that Izaya loves Shinra. Both Makio and Izaya (both kuudere) show restrained display of affection, act calm and nonchalant in interaction but will protect the person they love from behind-the-scenes and anyone who dares to harm the one they love will rue the day they dared to hurt them.
Iza-chan, congratulations. Your love for Shinra has finally been requited in another life.
This is definitely the best story in yaoi genre and one of the best stories in romance and overall, because it hits all marks. It has excellent art, amazing characters who are both admirable and endearing, has a coherent story line that sticks to logic and doesn't ruin itself for meaningless drama, and respectful treatment of all kinds of relationships.
Most authors in shoujo/josei/yaoi romances try to create an elaborate, complicated plot that they care little about just as an extravagant wrapping for stories that remain basically a simple romance or porn. But the plot is never their chief concern. The plot and even the characters are very inconsistent because they solely exist to create emotionally charged situations as and when convenient.
But this one is an extremely smartly written story. The author did not bite off more than they could chew, paid attention to pragmatic depiction of their theme, stuck to few elements and executed them better than anyone else. A truly magnificent job. One of my favorite things about this story that I rarely find in others is that this is a romance and our main characters are lovers but their relationship as lovers does not overshadow their identities and responsibilities as individuals. As an example, one of my favorite scenes in the story is ch 6 pg 20-26.
