Searching for a yaoi manhwa I read!!

I read this yaoi where the seme and uke don't end up together. The seme had a crush on this other female sunbae, lived together with the uke and was returning from the army at the start of the manhwa. Eventually after pining after the seme for ages the uke gives up on him and moves out to the second lead's home and they end up together at the end. But the seme actually falls in love with uke by this time but never acts on it and just lives on with the unrequited love
