that ex-president reminds me of one of the character in cheese in trap. the black haired guy with a very manipulative mind. their smiles are similar even that 'NICE' guy act is similar. maybe the ex-president will also be like that. they can be so nice to the ones they like but absolutely terrible to the ones they dont.
I like stories like this. A mature sexy uke and a younger seme. I read a story like this and in both manga the sex scenes really show that the couple care for each other.
