This is all I remember:
- It's a shojo
- the MC and ML are going to the same college (I think)
- the MC and ML both have black hair (I think)
- it should be ongoing (at least it was last year)
- I remember them being in a sports club or something and they go hiking a mountain where the MC hurts her foot so the ML has to carry her back down. Also I think he buys or looks for jewellery for her??

This is all I remember. Please help me, every guess is appreciated!
