Looking for manga: it was a serious title(tone-wise), pupil(boy) and teacher(woman) romance.

I remember there was one chapter with a heavy rain and someone got lost, the teacher probably. Our boy went looking.

Sounds a lot like "Sensei wa Koi o Oshierarenai."

Even if its not the one your looking for, I still recommend it pretty decent read with a cute ending.

Thanks for the recommendation, I might check it out sometime when I'm not maxed out on cute stuffs. It's been a while since there's been anything serious out there(think Death Note, Tokyo Ghoul, things like that).
