O-Negative

Five students nervously await the candidate announcements of University, and are accepted into the Faculty of Fine Arts.

The students attend their first drawing class, and must attend the hazing later on. Foon and Prim are called out and must perform for everyone.

After everyone asks her whether they have class the next day, Prim creates a group-chat for them all. Puen suggests Group O because they all have the same blood type.

The students are asked to draw a landscape, without being too detailed, that reveals their feelings about the area.

The friends stay out drinking and take Chompoo home when she has too much. Only then do they realise Foon is not with them.

Puen talks to Art about his feelings for Foon, and admits to wondering whether she feels the same way about him.
