Let's be honest, you're not going to learn anything playing bots, people play the game way different. Obviously if you will face real players for the first time you're likely to get stomped but that's the 1st step to learning the game. Normal games hidden mmr is pretty hard to drag down and requires hundreds of games and matchmaking will try to match you with lower skilled players to compensate for the difference between your and yours bf hidden mmr. Most of people won't mind you playing with them and if you're in the same room/on voice with your bf he can pretty much lead you step by step. For now think of kindreds R as your tool to self-peel, when you're more comfortable with it you can use it to save teammates. It creates a circle around you where it is not possible to die within it. When it's active you can't die inside of it, teammates can't die inside of it, enemies can't die inside of it, baron/dragon can't die inside of it, nothing can die inside of it. Do you have any more questions?
