Short guide for which actions you need to take to get ending 2, pure love.
Day 1 dont let bob eat snacks alone with ria.
Day 2 dont give money
day 3 kick the barrel next to village heads house door until bob gets out.
Day 4 talk to bob the "maid" in village heads kitchen.
Day 5 beat the ambush and choose to hurry back to ria
Ending 3 is when you fail to get other endings,
ending 4 is when your love points are lower than bobs (ero status)[losing on night 5 halves your points]
ending 1 is netorase i think?
