Witch Training Manual: My Water Magic Is Wrong

[Witch + Time Travel + Raising/Childhood Romance + Slice of Life + Female Lead]
Wayne traveled through time.
He transmigrated into the body of a nobleman's illegitimate son, thinking he could finally relax and enjoy life, but he accidentally stumbled upon the truth.
His cheapskate father rose to power by selling his body, and now he's plotting to sell his son, intending to sacrifice his innocence.
To avoid being violated, Wayne fled overnight and hid in a border town, becoming a priest.
Then he awakened water magic.
Others' water magic: attack, defense, control.
His water magic: healing, soothing, and making people weak in the knees.
For three years, he used those hands to cure patients in half the city and became the most beloved object of repentance for the city's wealthy ladies.
The church's vice-deacon wanted him to go to the border and die.
I never expected it would be such a big help to him.
They successfully bought two excellent witches from the slave market.
Ice witch, fire witch.
One is prone to tears, the other is carefree.
One wanted to marry him, and the other wanted to marry him too.
Wayne stared at the messages on the panel, lost in thought:
What happened to the witch being a calamity?
How come they all become submissive wives in his eyes?
Fine, I'll raise it then.
Anyway, I'll have company on the road.
[Note: If she's well-cared for, she's a wife; if she's poorly cared for, she's... well, she'll still be a wife even if she's poorly cared for.]
