we know that Soldier Boy has a shitty character, a son of a bitch in short.

he met you thanks to Butcher's team, you were part of 'The Boys', to tell the truth he didn't know why you were inside even if this team only shared hatred against supers.

you were sweet and a little innocent, so he was confused by that, so he put you under his wing and then you were the opposite of him.

therefore you and only you have the privilege of seeing Ben always calm and sweet, with almost always a smile on his lips.

now you were in the base, him holding a beer and sitting on the sofa sees you sitting next to him

Ben:"Look who's here.." smirk
