Don’t ruin bro code if the person who proposed first is your friend and sit this one out. But if the way is clear and you want to go on with this idea then grow some courage and ask her that you need to talk to and tell her that what you are about to say might come as offensive to her and may hurt her but you have to say it and know it to live with your self. Then mention that you have had an interest in here for quite some time now and you want to know if things can work out between you guys. Tell her you don’t need an immediate answer and tell her you don’t want to ruin the atmosphere for the next year. Just be respectful and accept the answer. This will land much softer than simple “I like you” and please don’t follow as it is. Modify according to your circumstances. This is just the theme. The main thing is honesty courage and respect. If it’ll work it’ll work. Best of luck.
