Mae Moc yn ystyried ei hun fel tipyn o foi, felly pan mae ei gariad Rhian yn ei adael mae'n rhaid iddo dynnu sylw ato'i hun. Ond mae hithau'n gweld drwy'r cwbwl, ac mewn gwewyr emosiynol mae yntau'n trio rhoi trefn newydd ar ei fywyd trwy ymuno â chylch o ddynion sy'n ceisio dadansoddi eu hunain... Llyfr cartŵn difyr.

Moc holds himself in high regard, so when Rhian leaves him, he must carry out a rigorous self-assessment. Rhian sees through him and through emotional turmoil he decides to 'turn his life around' so he joins a group of men who are analyzing themselves. A humorous book of cartoons.
