Aigu, can you imagine having to live with him all the time, with his parade-ground voice? Arghh. Out of courtesy, maybe I could stand one date, if I were Seochil, but if he didn't lighten up, no way. Take the man to a masseur, something, just stand down, soldier. I'd spend all my energy trying not to yell at him. Here, pet this cat. Please, relax.
LOL! He'd probably have either a very good reason why military men don't pet cats, or a very good reason why he agrees it's good for a soldier's health to pet the cat, and therefore he will dutifully pet it.
Reminds me of how Seolchill always says she eats and sleeps well no matter what, because she's a soldier. And now that she's not doing so well, the older sister is saying it about her instead.
