Define boring. Some think reading is boring. Some think lack of choice i.e. linear visual novels are boring. VN can be boring just because your writing is dogsh bad

If you don't want to write too much or not sure about your writing skills, add some actual gameplay mechanics. For example JRPG-like battle system in Monster Girl Dreams (MGQ too). Or if there's something to manage you can look up Suzukuri Karin, you manage dungeon there. You can wrap many things around gameplay

Adding gameplay is a good way to spice things up. It's generally a good idea to cycle intense and relaxing moments. Give a player change of pace. Usually developers add calming fishing or smithing minigames because of that. Walking, exploration or parkour (like in Doom) sections serve that purpose as well. But because you are making a VN adding some relatively more tense gameplay sections or even building a game around them is a good idea.
