as itsara said it's impossible to change from bottom to top if you mean that, but if you mean his like meter and love events there are quite a few ways! I'll start with one time events I can remember,
the first meeting if you tell him about what his wife did I believe he gets some like to you because you told the truth.
next the village being attacked if you treat his wounds right away and don't ask if he wants help, he gets some like.
if you discourage him from going to the bandit camp and help him with the wall and doing the right choices you get more like.
the first search if you go along and do the right choices again during both day and the night variants.
I don't know if this one is after or before the attack but I know it's for sure after the first search, this one being the confrontation. he starts getting mad and you have the option to get pissed and call him out or stay silent, choosing to call him out gets you punched but also more like and a cute scene of him opening up to us a little.
this is the "attack" I mentioned (it's just Bernard thought he saw Caleb and Logan was changing into a werewolf for the first time) if you choose to check on Logan and stay with him he gets like and a Love point and another cute scene after he wakes up.
I don't know if when he says you should have picked Bernard if it get's like but it might.
before you get the cure and save Bernard, you can give Logan wolves bane during the day and it gives more like to him one time and unlocks a continuous event at night until he's given Antilycan.
then "curing" him I believe gives you more like as well.
then after doing some events such as Barrel and Logan almost getting into a fight (Barrel didn't really care and was just being horny, Logan got pissed because that was gross. I would have sucked his dick but Logan ain't me lmao) the next event would be all 3 Bareshade expansions, and last I think is the country road event where you make a path to Ste's house. during that event if you do everything perfectly you get a lot of Logan like too. however all of those lead up to the next event, the one where he visit's your house in Bareshade. this is INCREDIBLY important. he comes in and offers some booze or wine and you start talking. mentioning his wife causes his to get upsetish but other things give like I believe. after your done talking though he gets super drunk and starts trying to fuck you. if you say yes if your werewolf like is high enough he turns into a werewolf and screws your brains out, but if it's low he stays human. either of these scenes come at a major cost though, it gives a black heart, and he will HATE you. just decline this scene and you get something both cute and depressing plus another good heart for him.
also, this is one I don't remember but I think it does give like too, that being the training the new guards for the watchtower upgrade with Logan and the drunk dudes. say he smells nice and it should give like I believe.
once you get the fair unlocked as one of the expansions you can also go to his house and invite him, again onetime thing but once you do if you make it fun, he gets more like with you and gives you a trinket he won from a game you play with him.
I think the next one Logan starts sneaking out of Bareshade and you follow him into the wolves' den where you fight the Alpha, and you can encourage or discourage transformation with him but either one you get more like.
the swamp werewolf thing is next, do the event where he goes to your house in Bareshade first though because if you don't I hear you can get soft locked out of that event forever. this one is triggered after the one mentioned before is completed and has a lot of steps to start, the game guides you in the right direction though so just follow what the game says and you'll get both his third Heart and a spicy scene with him as a werewolf or human depending on what you choose.
the last thing should be the diabosite weights. once you have 3 hearts (I think this could be not a requirement but if it doesn't show up and you only have 2 maybe it is) and diabosite unlocked you can ask Blake to make some for Logan and he will thank you after recieving them. you can also then suck his dick if you ask to watch him workout when you have 3 hearts with him.
that should be it for onetime events, now repeatable.
work out, doing this has a limit eventually but it's a good start.
getting him wood from the quest that appears after completing his first quest to fetch Oak Wood, his new Axe from Blake and water lilies.
if you gave him wolves bane at night you can visit him and until you have the "cure" you can just stay with him and get more like for a while. this also has a limit but it's not easy to hit if your actively trying to get the Antilycan lol.
after that or a different quest from him you can get a quest to give him more Antilycan and wolves bane so he can suppress the wolf and that gives more like too everytime for a certain amount of times.
certain gift's I believe are able to be given multiple times and give like each time so those too. idk since I haven't tried but with other characters it works so prolly him too lol.
if you do the stay with Bernard the whole day thing sometimes Logan will come in and if you go with him and work in silence it gives more like too.
that's all I got for now. if anyone has anything to add that would be nice!
