BIOGRAPHY

Ciize Rutricha Phapakithi and Kapook Ploynira Hiruntaveesin first shared the screen as girlfriends with a problem. In Pluto (2024) Ciize played Pang, Pim’s girlfriend, caught up in a messy love triangle with Kapook’s Pim and Earn Preeyaphat’s Jan. Ciize then joined Kapook in Revamp: The Undead Story and Girl Rules, and in 2026 the two co-starred in Enemies With Benefits, the series that brought Ciize wider recognition.

Rutricha Phapakithi (รัตท์ริชา ประภากิติ), nicknamed Ciize, was born in Bangkok on 23 September 1999 as Apichaya Saejung. In July 2023 she announced that she was changing her legal name, because someone else shared her exact birth name. She went to Satriwitthaya 2 School and earned a bachelor’s degree in business Chinese at Bangkok University in 2022.

Her screen career began in 2015 with Cherry in Wonder Teacher, followed by May in Kiss: The Series and Mochi in My Dear Loser: Edge of 17. Her first main role was Nik in the 2018 web series YOUniverse, opposite Chimon Wachirawit Ruangwiwat. After she signed with GMMTV she debuted in November 2019 with the girl group Sizzy, first called Sissy, and stayed until the group disbanded in October 2024. Supporting parts kept coming in the meantime: Lyla in Who Are You, Pang in Tonhon Chonlatee, Thong Hansa in The Prince Who Turns into a Frog, and a main role as Nan in the mystery miniseries The Comments.

2024 was her GL year. In 23.5 she played Alpha, the academically gifted student council president and older sister of Milk Pansa’s Ongsa; she was Fai in We Are and Baifern in ThamePo: Heart That Skips a Beat before Pluto. In 2025 she hosted Chuang Busking Day, the event for Chuang Asia: Season 2 trainees, switching between Thai, English and Chinese, and played Jin in Boys in Love. The 2026 list adds Airy in Girl Rules, Proud in Enemies With Benefits and Lha in Scarlet Heart Ullavee, with Ditto and her lead as Sitang in Be Mine still to come.

Here is the thing about Ciize’s list: it is eleven years long and almost all of it is support work. That makes Be Mine worth watching for. Sitang will be her first lead since The Comments in 2021, and the girl group years sit right in between.

My tip: start with 23.5 and then go to Pluto. Alpha is the composed older sister who has everything in order, and Pang is the friend whose love life is all knots, so the two roles show how wide her range runs in a single year.
