He has perfect scientific thinking and is a genius in the mathematics department, but he is as stupid as Rilakkuma.
He has an optimistic attitude towards life, and he always flies by at a low altitude during exams. Although he has been muddling along, he has fallen in love with the Rilakkuma senior.
He doesn't believe in feelings, nor does he.
Is it just two people playing with each other, or are they already deeply involved?
