Help me..

Can someone help me find this manhwa im been looking for??
The mc works at a company and tries to find a new apartment but he gets scammed so while he’s crying his eyes out while drinking someone with pink hair offers him to let him stay at their apartment which is shared with 4 other people. Im trying to remember this from the top of my head but I think there was a character who came back from the military and also the mc’s ex lived there.
