I honestly really like this manga but I don’t think that minjoon is completely stable like he automatically assumes that he will sleep with the dad just because they will share a bed.
I don’t know it just on his part feels like he thinks that him and the dad are dating already but they aren’t yet at that point.
This I got from reading the Spanish raws

The painter not telling the master what happened only makes it look like he ran away from the master after he showed him his Vulnerable side by saying he loves him.
Now the master has always from the start been unstable and he clearly went through some sort of traumatic event that made him the way he is and just because he said he loved the painter It didn’t imply his traumatic past would simply evaporate.
This started at like no warning just slammed right into you no care in the world
I ACCIDENTALLY UNLIKED UR COMMENT SORRY
No worries (⌒▽⌒)
