Both manga are called Hapikon! ~Ōji to Sekai Ichi Happy-na Kekkon~ and honey ♥ days both done by Chistose Yagami.

I really want to read them too, not because of the artwork but the story seems to my liking, (honey ♥ days is about a girl living with her childhood friend slash popular idol and Hapikon is about this girl, and she touches the chest of two princes which means proposal to them. xd )

Edit: i made a mistake he s not a popular idol but a famous actor. xd in a well paid fame profession anyway.
