Called Summer Lesson: Miyamoto Hikari Second Feel, the pack will give you six more outfits for Hikari and give you situations where you can sorta-kinda touch and interact. One of which allows you to help Hikari treat an insect bite or feed each other cake.
The first pack, Summer Lesson: Miyamoto Hikari Seven Days Room, launched earlier this year in October.
For those unfamiliar with the game, you basically act as the summer tutor for Hikari Miyamoto for a week, and you get to interact with her though a handful of situations and conversations.
An English subtitled release for Summer Lesson is coming early 2017 for the Southeast Asia region.
