Fold an original six-square net mentally from face B, checking opposite pairs and planar hinges without inferring cube relations from flat distance.

Faces far apart on paper may meet after folding, and lack of a flat shared edge does not prove lack of a cube edge. Read a defined cube net in ManYue using six labels to track folding. No automatic recognition, 3D model or cutting exercise is required. Keep the specified grid and personal reasoning separate from the original artwork.
## Record the six square positions explicitly
Record edition, page, panel and caption. Confirm six equal squares forming a cube net, not a cuboid, multiview drawing or collage. The original grid has horizontal row A, B, C, D, with E above B and F below B; all other cells are empty. Relative to B, A is one left, C one right, D two right, E one up and F one down. Use one unique label per face. If a square is cropped away, mark the evidence incomplete instead of supplying a familiar sixth face.
## Count shared paper edges, not touching corners
The flat shared edges are A–B, B–C, C–D, B–E and B–F: five. Corner contact is not a shared edge, and a dotted annotation may be an explanatory arrow rather than a hinge. List all five and confirm full equal-length square edges meet. A and E being diagonally close does not create a flat hinge. These are folding connections, not a character’s route; zoom or screen rotation does not change their count. Record explicit cut marks separately.
## Fix B and follow the neighbouring faces
Treat B as the reference. A and C rise from its left and right, while E and F rise from above and below; D, attached beyond C, closes opposite B. Keep folding and viewing conventions consistent rather than mixing inside folds with arbitrary back views. A hand-drawn cube may help, marked not to scale and not presented as an app-generated model. Track face and edge relations first. Directional patterns need separate checks of printed side and final viewpoint before assigning left or right.
## Pair all opposites into exactly three pairs
The opposite pairs are A–C, B–D and E–F. Each face has one opposite, making three pairs. B–E cannot be opposite because their shared paper edge remains a cube edge. Check that every label appears once in the opposite list. A cube face also has four neighbours, which does not contradict having one opposite. Do not call every hidden face the back and conflate them: facing away from a viewer is viewpoint-dependent, while opposition is a fixed relation between two faces.
## A missing flat hinge can become a cube edge
A and E share no paper edge but become neighbouring sides and meet along a cube edge. A cube has twelve edges: five retained hinges and seven formed by joining boundary pairs. Six squares supply twenty-four edge occurrences; five shared edges remove ten boundary occurrences, leaving fourteen segments paired into seven. This checks edge relations for the specified valid net. It does not prove that every six-square arrangement folds into a non-overlapping cube; that still needs a folding check.
## Test an incorrect opposite pairing
Test the claim B is opposite C. Their shared flat edge already refutes it without arguing over an unclear perspective sketch. The claim A is opposite D conflicts with D’s closure opposite B and can be checked through the folding sequence. Keep incorrect controls in external notes rather than changing original labels. If a real diagram assigns letters differently, infer from positions again instead of memorising A opposite C. The letters identify this original grid, not a universal formula for cube nets.
## Check perspective and inside–outside conditions
If a comic shows three faces, first check whether the labels are pairwise adjacent, then examine pattern orientation. Opposites cannot form the three adjacent exterior faces of one opaque cube. Transparency, cutaways or collages of different states need separate treatment. For an arrow, record which shared edge it points toward rather than only screen-up. If printed side or cube rotation is unknown, keep orientation unresolved while retaining independently established opposite pairs; one uncertainty need not erase every relation.
## Leave and return to rebuild face and edge lists
Leave reading and return to the entire net. Cover your answers, rebuild the five flat edges from row A through D and E/F around B, then infer the three opposite pairs. Recalculate fourteen boundary segments forming seven edges and explain A/E adjacency after folding. Keep grid positions, hinges, opposites, viewing conditions, rejected candidates and unknown pattern directions. Success reconstructs relations from the diagram, not automatic marking or proof of every net, package size or manufacturing condition.
