Well, if you do the good/true ending route, you'll get to make a decision in december 24 in which whom to spend christmas eve, so if you pick one, the other will break up with you I guess :P
If you haven't started Temperance, then you're pratically screwed. It's the Day Care work, and you need to do it almost 20 times to get Max Social Link. Tower works the same, you need to do the Tutor work and need MAX ranking in understanding and diligence.
Focus on the Hermit (The fox) since it's extremely benefitial for your dungeon exploration, the price to recover SP will decrease massively once you reach Max rank.
