Gokuraku Doumei ("Paradise Union") by Emure 4 volumes-complete
Homare is trying to keep the onsen running while her mom is sick and with her dad gone. She has strictly imposed a no relationship rule especially when they have a new live-in staff. The story is slow and the characters showed some development in their stereotyped roles right exactly at the last scanlation. >.< The art has a familiar feel because I've read one the mangaka's work beore, 'Michibata no Tenshi'.
Thanks to Ashley for the tip.
