Anywhere in the game that there is a locked choice, usually requiring Max Affection from a girl... that requirement is ONLY for the specific chapter. So if it needs High Affection for Ah-young in Chapter 4, then you only need to pick the best choices for Ah-young in Chapter 4... not the earlier chapters. And all of these leads to Bad Endings.

There are also 2 achievements not tied to game choices. These involve voting on characters. Achievements and Chapter Progress give Thumbs Up (or Thumbs Down for bad ending achievements)... there is one achievement for giving 50 Thumbs Up and one achievement for giving 1 Thumbs Down.

Hidden Route achievements are also chapter-specific, and require making exact choices for certain characters within that chapter.

Achievement "Relationship development" awards at the end of the Chapter

NOTE: the game tells me I have 100% completion on the chapter, but the 4th Thumbs Up for 100% won't award to me... not sure why; maybe I didn't finish watching one of the scenes? Will double check it after finishing the game. Although the achievement for 100% completion on all chapters still unlocked when it was supposed to, so guess this doesn't matter. Not going to go re-checking every path on the chapter.

Achievement "Hearts Connected" awards at the end of the Chapter

For Ga-eun 100% affection, the Chapter 4 choices seem like they wouldn't matter, but you need to pick Ask for Bite and Best Views, since each of them have a sub-choice that gives +Ga-eun. Then in Chapter 5, you must go Lonely route and must pick Take a Break. The date options don't matter later in Chapter 5 as long as you get the +Ga-eun.

For Ah-young 100% affection, neither of the 2 choices that give +Ah-young matter which one you pick; they're worth the same. You want to go Lonely route in Chapter 5.

For Bit-na 100% affection, near the end of Chapter 2, you MUST pick Should Take More. The choice in Chapter 5 doesn't matter. I went Lonely route in Chapter 5, but might not matter.

For Ji-woo 100% affection, in Chapter 4, you MUST pick Big Boobs and Sorry in the Anime sub-section. In Chapter 2, I picked Her Body Changed (not sure if this matters). In Chapter 4, near the end, it does not matter if you pick Not Sure Who or Can't Tell; they're worth the same. You want Cosplay route in Chapter 5.
