"I tend to do my own thing and cheer Janet from the background. My support comes more from family and I also spend time with her children."
Like her elder sister, Sharon said learning that Eddie had proposed to Janet was surprising.
"Eddy had been in and out of her life. I remember the first time I saw him was during a farewell party at KTN, when she was going to South Africa," she said.
"When she was there (South Africa), I learnt they connected, and later, they started dating."
Sharon narrated how Janet put Eddie on the spot since he allegedly had a reputation out there with women.
"Janet really tried to ask about such and other things because, how would she know for sure?"
Sharon said Eddie was persuasive enough to win Janet's heart and even went out of his way to prove himself.
"The first day he came home and he had engaged her out of Nairobi, and they were sitting together and he was like, she is engaged," she said.
"I remember being surprised because, yes, they had been together and had dated, but that step was a surprise."
As a family, Sharon said they later switched the mood and helped plan her wedding.
"We helped with invitations and started planning for her wedding. But I can say, it was more of a surprise."
Janet and Eddie Ndichu tied the knot in a colourful wedding ceremony in 2015 at Chaka Ranch in Nyeri county. They allegedly ended their union a few years ago.
