My last recommendation for today is Sincerely, Mysterious by @Slimm
It's quirky, it's teenager love, it's goofy. AND the cringe, oh god, the cringe will kill you and the sweet moments will bring you back to life (don't say I didn't warn you).
The entire story is about chatting up your crush and them not knowing who you are. Fascinating, isn't it? Fair warning, our MC is not the smartest detective in town... If you're looking for something cute and realistically awkward, you've found it.
