As much as I don't really like Gunji, no, this is not his fault at all.
This is all fishfuck's fault.
Holy shit it's just as I suspected. Ryutaro caught Shingo. Well, no bicycle involved tho, instead it's a taxi.
...Wait, did Ryutaro catch Shingo with his bare hands? Did he seriously catch someone falling from 8th floor with the most precious assets to every surgeon? ...Holy shit. No way his hands won't suffer permanent damages from that, which might as well end his career as a surgeon.
Man, I'm saying "holy shit" a lot today.
