help me

So, I have this faint memory about a yaoi manga, the story begin with uke come home from his work and find a stranger-the seme- sleeping or maybe he painted, in front of his house in the middle of snowy night. It turns out that the seme was hugging a cat because the cat is abandoned just like him, uke save him and the story goes on, the problem is they can not express their love to each other, witch turn out into some serious trouble, I remember there are one more couple with the same problem and the two couple are betraying one another, like seme a with uke b and seme b with uke a. Well, that's all that I can remember, sorry with my messy words, english isn't my language u.u
