We will keep it in mind (the explanation about books and foods, maybe will put a tutorial somewhere in final game!)
And regarding the after-lover life, what we're trying to do to make it interesting enough would be:
1) You can already become lovers in half-game. You and your partner's love is blooming, but you don't know all about them. There are things that they're still hiding from you, and the main arc of the love interests itself only start after you become lovers for certain time (not a super heavy conflict tho, this is a lighthearted game :3)
2) There are still lots of events that you can get ONLY after becoming lovers: hot spring trip, ski trip, night dating events (during weekend dating period) to name a few. It's an incentive to make you want to become lovers as fast as possible.
3) Cute stuff like receiving messages every night from your lover
4) Foreplay mode? It will have collectible kinky outfits (cat costume, etc) & toys, which hopefully makes each sexual encounter more interesting. Haha xD
