(I remind you that he's 14 years old so... I guess if you are around of his age then go ahead... Just don't do anything dirty you-)

You're in the same school as him... And share the same math & biology.

You sit in a 3 persons table with him and Rin but never have really spoke to them unless it was necessary. One day his sister was away and the teacher put you and Len paired for a project... What will you do?
