Eren "Is Corporal Rivaiile in here? I'd like to ask him something..."
Trio "Just on time, Mr. Suicidal!!"

Eren "Hm? Say, Corporal...."
Trio "He's on to something already!"

Eren "Did you get a haircut? :D"
Trio "AHHHH It's the end for him!!!"

Rivaille "......Sure." *pinch*
Trio "Huh? Wait, he looks kinda happy!"

Eld "Oh, I see... The Corporal was nervous in hopes of someone noticing his unnoticeable haircut."
Petra "That means he was playing with his hair as a hint...!" *kyun
Gunta "Eren makes a great girlfriend...."

(In the background)
Eren "You look much more handsome, Corporal!"
Rivaille ".....I only got a simple trim."
Eren "Still, I think you look lovely!"
Rivaille "........MARRIAGE."
