I love this manwha, even if the plot was slow pace and make some people confused, I still find it really enjoyable to read. plus we also have a protective waifu who always fight beside him and always support him Knight Under My Heart tell a story of a high school boy being invited to be a beta tester for a new MMORPG, but little did he know he was trapped inside the game and the only way to be able to go back to reality is to beat the final boss. Despite of him being weak at first, and dies again again and again, he alwaysable to stand up and fight and never giving up till the end

I really hope this manwha is known by more people and hope that the plot will keep getting better and better.

Overall if you like Zero to Hero Manwha then it's for you. If you don't like it then it's fine,
even if there is a little romance here, but the story is very good.
