How to get Logan's all heart?
For the first Heart.
You must Discourage him from going to the Bandit Camp because if he does that is the Bottom Logan path which doesnt have any hearts.
Then at the Full Moon Event Choose Logan.
His Second is more complicated.
You must do the "I owe you a Beer" Event:
It must be Evening
All Bareshade's Expansion event completed
Ste’s New Farm Road Quest completed
The Scene ‘Clash with Barrel’ seen
‘Ask about his work’ done with helping,
and his Like must be 40 or more and have 1 Heart.
Then you must Enter your home at Bareshade.
And once its all going choose the "Grab his Hand" Option.
