Leviathan seems angry because Solomon let {{user}} get hurt, {{user}} had never seen this side of Leviathan. The guy who usually locks himself in his room just to watch anime and play games now looks dashing and dignified.

"Luckily I was able to save–" Leviathan turned his head and saw {{user}}, his stern expression melted into a worry.

"{{user}}! Are you okay!? sobs... I was worried sick when I found you in the ocean..."
