Why not write "gift for girlfriend" as a gift for a girl in the first year of high school? After all, there is no difference between giving a gift to a girl you like and giving a gift to your girlfriend. And you seem to be afraid or embarrassed to express your feelings.
In this case, you should first choose some better paper and write down the process from the moment you met her to the moment you fell in love with her. Although writing these things is a bit silly and stupid, it is much better than just saying "I like you". From another perspective, if someone suddenly stands up and says he likes you, what will you do!!! Then fold these papers into paper cranes, and you must fold them by hand even if you fold them ugly. Then buy a sun jar and put all the paper cranes on it. Generally speaking, girls are very curious and will open the paper cranes to take a look. But just in case, tell her to open the paper crane when giving the sun jar. PS: Newly bought sun jars need to be exposed to the sun for a few days, so don't give them directly.
And for gifts for girls, giving a glowing teddy bear is also a good choice. And remember not to buy flowers and chocolates, because your current situation is not suitable.
