Yn ystod y bore, roedd haul y gwanwyn yn tywynnu'n felyn ar lan y Bae Caerdydd.

In the morning, the spring sun was shining yellow on the shore of Bae Caerdydd.

Roedd adar yn canu, gan greu symffoni fach i ddechrau eu diwrnod.

Birds were singing, creating a little symphony to start their day.

Roedd Gwyn wedi treulio'r noson flaenorol yn poeni am ei ddyddiad cyntaf gyda Rhiannon.

Gwyn had spent the previous night worrying about his first date with Rhiannon.

Roedd yn awyddus i greu argraff dda ond roedd ofn iddo rywbeth fynd o'i le.

He was eager to make a good impression but was afraid something might go wrong.

Wrth sefyll ar y platfform, teimlai Gwyn ei galon yn curo'n gyflym.

While standing on the platform, Gwyn felt his heart racing.

Roedd y tren yn cyrraedd yn araf, a chyn hir, trodd Gwyn ei olygon tuag at Rhiannon.

The train was arriving slowly, and before long, Gwyn turned his gaze towards Rhiannon.

Roedd hi'n gwisgo cot las, gyda'i gwallt yn dawnsio yn y gwynt ysgafn.

She was wearing a blue coat, with her hair dancing in the gentle breeze.

Chwarddodd Gwyn i'w hun, a theimlodd nerfusrwydd yn lledaenu.

Gwyn chuckled to himself, feeling the nervousness spreading.

"Beth am fynd i'r bae heddiw?

"How about going to the bay today?"

" gofynnodd Gwyn, ei lais yn ysgafn.

asked Gwyn, his voice light.

"Perffaith," atebodd Rhiannon gyda gwên serchog.

"Perfect," replied Rhiannon with a charming smile.

Felly, teithiodd y ddau ar y tren, sedd wrth sedd.

So, the two traveled on the train, sitting side by side.

Trafodasant bopeth o'r tywydd i hoff lyfrau.

They discussed everything from the weather to favorite books.

Ond yn sydyn, cyhoeddwyd y newyddion – oedd gwaith ar y trac.

But suddenly, news was announced – there was work on the track.

Byddai oedi hir.

There would be a long delay.

Synhwyrodd Gwyn chwys oer ar ei dalcen.

Gwyn sensed a cold sweat on his forehead.

Rhiannon edrychodd arno gyda chydymdeimlad.

Rhiannon looked at him with sympathy.

"Dim problem," meddai hi, yn dawel.

"No problem," she said, calmly.

Pan safodd y tren, trodd Gwyn at Rhiannon.

When the train stopped, Gwyn turned to Rhiannon.

"Beth am i ni siarad am dy hoff atgofion o'r traeth?

"How about we talk about your favorite beach memories?"

"Daliodd siarad i droi'r amser, gan synnu at ba mor hawdd oedd cadw'r sgwrs i fynd.

He kept talking to pass the time, surprised at how easy it was to keep the conversation going.

Roedd hi'n chwerthin wrth gofio am anturiaethau traeth a phicnics teuluol.

She was laughing, recalling beach adventures and family picnics.

Pob gair yn gwneud iddo deimlo'n fwy hyderus, llai pryderus.

Every word made him feel more confident, less anxious.

Yn olaf, cyrhaeddodd y tren ar safle Bae Caerdydd, er yn hwyr.

Finally, the train arrived at Bae Caerdydd station, albeit late.

Roedd yr haul yn dechrau gostwng, ac roedd y cafeau yn brysur gyda phobl.

The sun was starting to set, and the cafés were bustling with people.

Mae golau'r haul yn taflu cysgodion hir dros y dociau.

The sunlight cast long shadows over the docks.

Roedd cyflawnder o flodau gwanwyn yn eu croesawu.

An abundance of spring flowers welcomed them.

"Mae hwn wedi bod yn ddiwrnod hyfryd, Gwyn," meddai Rhiannon, wrth droedio ar gyfer gwylio’r dŵr.

"This has been a lovely day, Gwyn," said Rhiannon, as they strolled to watch the water.

Roedd Gwyn yn teimlo'r llwyth yn codi oddi ar ei ysgwyddau.

Gwyn felt the weight lifting off his shoulders.

Sefydlodd bod ei phoeni yn ddi-sail.

He realized that his worries were unfounded.

Roedd wedi darganfod gallu i reoli ei bryder, gan sicrhau fod y dydd yn arbennig er gwaethaf y digwyddiadau annisgwyl.

He had discovered the ability to manage his anxiety, ensuring the day was special despite the unexpected events.

Roedd yr argraff dda yn sicr wedi cael ei greu.

The good impression had undoubtedly been made.

Mae gobaith newydd wedi dod i'w galon am ddyfodol eu perthynas.

New hope had come to his heart for the future of their relationship.
