When you have selected her you just need to pick the "Ask" option and ask her if she would like to go on a date with you.
In order to push the friendship to Lover you need to complete a date successfully with a kiss.
for a succeful date do i need to also choose all the options that give most happiness? or is it like a small chance that she'll kiss me?
Oh yes, you definitely need to pick the right options through the date to increase the chances of getting a kiss. Also giving the right gift increases those chances.
ok thank you
