I think that was the most unrealistic way of trying to go out on a person but i know it how hard can be to be sincere to the ones you actually adimire and confess to them
but hear my adivice, if you want to confess to someone always remember to build a relantionship first and when you have the right opportunity start by talking about some random stuff and slowly opening the persons defences before telling her you true intentions
a confession should not be using brute force but slowly talking out with the person and making her comfortable before talking to her about your true intentions
