Overview:
Second Girl's Happiness is a story about a guy who has hit it big developing a mobile game, but at the expense of his relationships with his friends. This is a story about rekindling those relationships, self improvement, and watching out for people trying to take advantage of you. And building a harem!

Chapter 4:

Accept Katrina's help building the harem and be as submissive as possible to her.

Accept Katrina's help building the harem, but stand up for yourself

Don't accept her help with the harem and later go with her to pick up the alcohol at the bar.

Don't accept her help and don't go to the bar. Also be as confident as possible.

These four paths will let you see all the content. There is also a future sub-path planned for those who did not forgive the girls, as well as one for trying to make the harem on your own, but keeping your confidence low. With the addition of these routes I had to change a couple of variables in the earlier chapter, so you will need to start a new game. Remember that you can hold down ctrl to skip text.
