The premise of this story is interesting the execution was lack lustre.

A supposedly introverted student (with very dyed hair) tries to not be noticed?
A jock type student who loves loud extroverted friends and sport falls for his neighbour after a brief glimpse and a few conversations?

Issues of how these two extreme types make for a good relationship are attempted, however, the power dynamics are uneven and despite all the 'green flag' behaviour of God he overplays the benevolent protector to the point of nearly creating a 'Daddy' personna.

Luckily this is curtailed. I felt the jump to intimacy was premature, they had so little time together beforehand so this trip away and shared tent scenario seemed rushed, especially as we are led to believe Diew does not reveal much about his past or feelings.

The grandfather is terrific offering the whole hearted support in place of the dead father. The Mother is well depicted because her harsh expectations are what has added to her sensitive son's inability to voice his needs and to feel not 'normal' enough. The ex boyfriend reveal is a good explanation of what can occur when first love feelings get trampled on. Diew has already absorbed the not normal message from his mother and now it is repeated exposing his greatest fears. So the little turtle shrinks back into his shell.

The turtle metaphor is apt but like other viewers I wanted both Diew and the turtle to have more freedom.
