Kigengire no Hatsukoi

Uno has a love he can't forget. He always felt unrequited love for Murakami, who everybody liked even after graduating from university. He tries to end his love after going to his friend's wedding and possibly meeting Murakami there again, but he finds out that Murakami is in debt and went missing! Murakami lost everything and became homeless. Uno takes him to his house to end his love and begins living with him. (Source: Libre, translated)
